The healthcare industry is well aware of the issue of limited resources. By properly managing available resources, waste may be minimized. Bangladesh is a developing nation with limited resources, hence it is essential to estimate technical efficiency in this circumstance. Health care efficiency in the developed world has long been examined using Data Envelopment Analysis (DEA). However, few studies have used DEA to evaluate the effectiveness of healthcare delivery in emerging economies, especially in Bangladesh. A total of 24 community clinics in Kushtia were chosen at random for this study, and their technical efficiency was determined using the DEA method. The goal was to assess health centers’ levels of efficiency and provide recommendations for improving less effective centers’ performance. Input-based Data Envelopment Analysis was utilized to evaluate technical efficiency. The first category comprised of twelve prominent public hospitals. In this study, the number of outpatient visits was both an input and an outcome variable, whereas physicians, nurses, drugs, and other medical supplies were input variables. The Malmquist index was also utilized to assess efficiency gains and losses over time in community clinics. The eleven surviving community health clinics ended just inside the border. Based on their average efficiency rating, the facilities could accomplish the same goals while consuming 42% less inputs. On average, each CC created garbage worth TK. 0.14 crore. Across the board, production grew during the study periods. Overall, the findings suggest that public health centres are extremely inefficient in their delivery of health care and that substantial savings may be achieved by implementing steps to reduce waste.

This article examines the effect of the increase in the cost of living on the age of marriage in Iran. Age of marriage, reproductive age and number of children are used as dependent variables and income, unemployment and living expenses are used as independent variables in this article. The required data was collected from the distribution of 384 questionnaires among single and married men and women. For data analysis, one-sample t-test and Kolmogorov-Smirnov test were used. According to the results obtained from the data analysis, with the increase in the cost of living, the age of marriage and reproductive age also increases, and also with the increase in the cost of living, the desire to have more children decreases, and there is a significant relationship between income and the number of children. This is despite the fact that there is no significant relationship between unemployment and marriage age, if unemployment and income and living expenses are dependent on each other, but in the statistical population of this article, unemployment does not explain its effect on marriage age correctly. Also, there is an inverse relationship between the amount of income and the age of marriage.

Investigation of budget deficit and government debt relationship with economic growth is one of the important topics in macroeconomic literature; Hence, the present study examined the role of budget deficit and government debt on financing the economic growth in 40 developing countries between 2010-2019. In this regard, the economic growth was defined as a function of financial development, budget deficit, government debt, government expenditure, human capital, inflation rate, trade freedom, and the interaction of budget deficit and government debt with financial development. To examine the relationships between variables, the panel data econometric model and the feasible generalized least squares method were used. The estimation results showed that in developing countries, financial development had a positive and budget deficit and government debt had a negative and significant effect on the economic growth. Also, the interaction effect of budget deficit and government debt with financial development on economic growth was negative and significant that showed budget deficit and government debt play a negative role in positive relationship between financial development and economic growth. In addition, government expenditure, human capital, and trade freedom had a positive and significant effect on economic growth, while the inflation rate effect on economic growth was not significant.

Agriculture is one of the most important sectors and driving factors of the economy of Bangladesh, which plays a significant role in the prosperity of large rural communities by increasing productivity, income, and creating employment. Presently, this sector has faced a severe challenge in its production, due to the construction of unplanned infrastructure in rural areas. This study investigates the effect of rural infrastructure on agricultural production in Bangladesh. Using the purposive sampling technique, 50 respondents were interviewed through a structured questionnaire to collect primary data from six unions of Sadar Upazila in the Kushtia district. Statistical methods of multiple regression and paired-sample t-test have been utilized to analyze the collected data. The results of the multiple regression model show that the co-efficient of cultivable and infrastructural land size is statistically significant at 1 percent of level, which depicts cultivable land positively affects agricultural production, whereas infrastructural land negatively affects agricultural production in the study area. This means that infrastructure built on cultivable land has reduced agricultural production. Paired-sample t-test result also shows that the mean difference between agricultural production before and after constructing infrastructure is TK.134847.94 per year. The primary reasons for the construction of infrastructure in the study area are unanticipated population expansion, urbanization, unplanned human settlement, and a rise in nuclear families. Lastly, suitable policies have been offered to develop the infrastructure as well as agricultural production in rural areas.

This paper uses a mixed market model in which a state-owned public firm and a private firm produce complementary goods and reassesses the welfare effects of production subsidies. The paper examines four regimes: mixed and private duopoly, each with and without subsidies. In the regimes without subsidies, a one-shot Cournot-Nash game is considered. In the regimes with subsidies, the following two-stage game is considered: At the first stage the government chooses the subsidy level to maximize social welfare, and at the second stage each firm observes the subsidy and simultaneously chooses its output level. The paper presents the following two main results. First, if production subsidies are used only before privatization, then there is a reduction in social welfare. Second, if production subsidies are used before and after privatization, then social welfare is not changed by privatization. The paper finds that the results are the same as those obtained by White (1996) that examines the welfare effects of production subsidies in a Cournot mixed market with homogeneous goods.

One of the most significant sources of government funding that has an impact on social and economic trends is tax income. One of the most significant elements impacting macroeconomic variables, particularly tax income, are exchange rate swings. In this regard, the current study has looked at the impact of currency rate changes on tax receipts in the Iranian economy from 1979 to 2018. The World Bank, the Iranian Statistics Center, and the Central Bank of the Islamic Republic of Iran's economic time series databases were used to extract the necessary data. To do this, the actual exchange rate fluctuation was first calculated using the Generalized Autoregressive Conditional Heterogeneity Variance (GARCH) model, and the required relationships were then estimated using the Autoregressive Distributed Lag (ARDL). The study's findings indicated that increased exchange rate swings when a firm is open and have an impact on tax income and put it at risk, which causes a short-term decline in tax revenue.

The main objective of this study was to empirically examine the influence of globalization on income inequality in Nigeria from 1986 to 2021. The income inequality was represented by the Gini coefficient while globalization was measured by key indices like foreign direct investment, remittances, and trade openness. With the use of the autoregressive distributed lag (ARDL) approach which was as a result of the stationary of our series at levels and first difference as reported by the Augmented Dickey-Fuller unit root test, the study observed that a long-run relationship exists amid inequality and measures of globalization. In the short-run, it was realized that foreign direct investment, remittances, trade openness, and urbanization aided in reducing income inequality in the short-run while inflation accelerated income inequality within the study period. In the long-run, the only measure of globalization that significantly reduce income inequality is remittances; while foreign direct investment significantly increased income inequality in the long-run. the paper concluded that it is not inevitable that measures of globalization have different influence on inequality of income and wealth depending on time.

The study aims to analyze factors that affect income of the fish pindang business in Mlaten and Kedawang Village, Pasuruan Regency. The research respondents were all fish processing business actors, totaling 24 business actors in Mlaten Village and 26 business actors in Kedawang Village. Data collected through interviews with respondents, and analyzed with multiple linear regression models. The results showed that income of the business in Mlaten Village was simultaneously influenced by price of raw materials, business experience, number of workers, education, processing facilities, firewood, and amount of salt. Partially, the income was significantly influenced by business experience, number of workers, and processing facilities. In Kedawang Village, simultaneously, all of these variables also have a significant effect on the income. But partially, business experience, processing facilities, and the amount of salt have a significant effect on the income. Most dominant factor is processing facilities.

The handloom textile industry, one of the significant labor-contributing industries in Bangladesh, provides income and employment opportunities for a sizable section of rural labor. However, in recent years, the handloom textile industry has been experiencing several problems in its production. The residents of three Upazilas in the Sirajganj district rely directly or indirectly on this sector. This study will examine the issues and opportunities of the handloom industry in three Upazilas of the Sirajganj district in Bangladesh. The district of Sirajganj was chosen as a purposive sample and used the multistage random sampling method of fifty handloom units from twenty villages in Ullapara, Shahajdpur, and Belkuchi Upazila. The Cobb-Douglas production function is used to identify in this case to assess the variables' impact on the Handloom sector's annual income. Labor, input, and education coefficient is significant at 1 percent of the level. On the other hand, capital has negatively impacted the handloom industries and is also not statistically significant. Despite experience positively impacting the handloom weaver's income, it does not influence statistically significant. The estimated capital coefficient of -0.208, and the approximate labor cost is 25.73. Major problems of the handloom industry in the high rate of fabrics and colors. These results suggest that labor is a vital part of the handloom industry and with the posting of workers, handloom output rises as well.

Vannamei shrimp farming on a mini-scale plastic pond ("busmetik") in Pasuruan Regency has been implemented since 2015. This study aims to analyze financial feasibility and potential for busmetik development in this region. The research was conducted in three sub-districts with a population of 120 farmers. Sample was determined by simple random sampling and 37 farmers were selected. Data collected through interviews, and analyzed by financial feasibility and SWOT. The results showed that busmetik vannamei shrimp farming in Pasuruan Regency was feasible to be developed based on investment criteria: R/C and B/C greater than one, short payback period, BEP price and production lower than real price and production, positive NPV, and IRR is higher than bank interest rate. Sensitivity analysis on the decline in production and prices by 20% resulted in the conclusion that this business is just feasible. Analysis of internal factors (IFE) and external factors (EFE) resulted in six strategies for developing vannamei shrimp farming business with busmetik technology. Those strategies were to classify product sizes based on quality; increase production volume with optimal land use; integrated production management; product differentiation; training program planning; and work with third parties for assistance. Government and investors can promote the business by supporting financing, providing integrated production management training in order to increase production and income of farmers.

The SARS COV2 pandemic hits the life and livelihoods of millions and consequently slows down the world economy. The pandemic hits hard the specific social groups due to travel restrictions/bans and other regulations that affect their income and consumption patterns. The goal of this paper is to find out whether the pandemic has any effect on consumption and income patterns among consumers in rural settings. To implement this study, structured questionnaires were sent to respondents and collect data from 180 samples living in rural areas of four different administrative districts in Bangladesh such as Rajshahi, Bogura, Naogaon, and Natore. Using paired sample T-test (parametric) and Wilcoxon signed ranked test (nonparametric) test found that pandemics had a significant effect on the pattern of consumption and income in the northern area of Bangladesh. While the Keynesian method of income determination shows that the MPC before the COVID-19 pandemic was 0.31 and during it was 0.37. This shows that consumers would like to consume at a higher level compared to them before the COVID-19 pandemic. Overall, the study revealed that though the pandemic significantly affect consumers’ income to reduce, consumption levels inclines fuelled by the fear of panic buying during the pandemic. Government should have preparedness to provide essential goods during any natural disasters or pandemic-like events.

Considering the emotional behavior of investors in the cryptocurrency market, this paper comprehensively explores the sophisticated relationship between Bitcoin investor sentiment and gold price movements. The purpose of this study is to examine the impact of the gold price on investor sentiment of Bitcoin market traders and investors using monthly data from August 2020 to August 2022. The impact of oil prices on investor sentiment was examined using the Pooled Mean Group (PMG) method. The PMG approach considers short-term and long-term relationships between series and provides reliable results in the context of dynamic heterogeneous panel models. PMG implementations in all models show the short-term and long-term impact of the gold price on investor sentiment. The results also suggest that gold prices are positive and significant in the long run across all models, and that behavioral factors such as consumer sentiment and global economic stability are important in controlling gold prices at shorter time resolutions. Precious metals have had a positive impact on the Bitcoin market,

Nowadays, the study of the share of households' health expenditures in their total consumption expenditures and its impact on the well-being of households and society has become an important issue as it is applied in policy and planning by government officials. This paper aims to examine the impact of changes in the share of health expenditures in the basket of total household consumption expenditures and to show that small changes in the variable have significant effects on consumption, desirability, and, consequently, the well-being of society. The results of this modelling suggest that a decrease in the share of household health expenditures leads to an increase in other household expenditures and, consequently, increases household welfare by an increasing utility. The reason for this is that by increasing its health and medical expenditures, the household must reduce its consumption of other goods, which decreases its total utility. It should be noted that this decrease is due to the fact that households are less inclined to spend a larger share of their total consumption expenditure on health services. An increase in the share of households' health expenditures in their total expenditures leads to a decrease in welfare, and a decrease in this share increases household welfare. However, factors such as the inefficiency of the insurance system, poor health system monitoring, and problems in accessing and using health services can have a major impact on households' acceptance, desire, and use of health services and should be considered a serious problem.

This paper examines an oligopoly game model with a concave demand function where labor-managed firms compete in quantities with each other. There is no possibility of entry or exit. The timing of the game is as follows. In the first stage, each labor-managed firm simultaneously and independently chooses the level of social concern. In the second stage, each labor-managed firm simultaneously and independently chooses whether to offer lifetime employment as a strategic commitment device. In the third stage, quantity competition takes place. This paper examines the reaction functions of labor-managed firms in the model. First, the paper presents the reaction functions of labor-managed firms in the game model. It is shown that the reaction functions of labor-managed firms have both upward and downward sloping cases. Next, the paper provides a simple example to support the above result. This example shows a case in which the reaction functions of labor-managed firms are downward-sloping.

In this article, we provide an in-depth study of the link between global commodity prices and the shocks market. Many Middle East countries are exports dependent and rely heavily on the global price of their primary commodities to make rational economic decisions. It is against this background that this study investigates the level of interdependence between global commodities prices and stock market returns in selected Middle East countries. For this empirical investigation, the two largest stock markets were selected based on market capitalization namely Tehran Stock Exchange (TSE) and Saudi Stock Exchange, TADAWUL (TASI). Specifically, we examined the relationship between global commodities prices and stock market returns and the direction of causality between the variables following Eagle Granger causality procedures. In addition, we determined the effect of global commodities` price movement on stock market returns using the ARDL estimation technique. The results of our analyses show that there is a significant long-run relationship between global commodities prices and stock market returns. Also, there exists a largely bidirectional causal relationship between global commodities prices and stock market returns in the two markets. Furthermore, the results of ARDL estimation reveal that global commodities prices have short-run and long-run effects on stock market returns in the two markets. These findings are robust to a battery of robustness checks. These results support the investor's decision-making process. In addition, the results of this survey are important for policymakers to strengthen the stock market to drive economic growth.

The attempt in this study has been to detect the influence of foreign exchange reserves on import demand in Nigeria. With data spanning from 2000 to 2020, we estimated the long-run and short-run import demand function using ‘fully modified ordinary least squares’ and ‘error correction model’ respectively after we established that our variables were integrated of the first order and that cointegration exists. The long-run import demand function pointed out that the effect of foreign exchange reserves on import demand is positive but insignificant but such effect turned negative and significant in the short-run. Import price was also noted to put forth a negative sway on import demand with its effect being significant. Income was observed to wield a positive long-run influence on import demand while the effect of exchange rate was positive and significant in the long-run but became negative and significant in the short-run. By the elasticity coefficients, income elasticity put forth a greater influence on import demand compared to every other variable with the coefficient being greater than unity. It therefore becomes pertinent for actions toward reducing the income coefficient to less than or equal to one to be instituted. It is critical that import demand management be regarded as an aspect of an inclusive stabilization strategy. Imports should be targeted as part of this effort to compensate for shortfalls in domestic production. Furthermore, strategies that reduce government spending or raise taxes (contractionary fiscal policy) could reduce income growth which is a chief driver of import demand.

In the theory of microeconomics, in discussions related to consumer behavior, it is usually assumed that the household acts as a decision-making unit like an individual, and for a household, a budget constraint and a utility function are considered. As a result, only the general behavior of the household will be observable and analyzed. Since the 1980s, this method, which is called the Unitary Household Model, has been criticized theoretically and empirically, and issues such as the inequality of household members have been raised. In contrast to the Unitary Household model, Collective Household Model was proposed in consumer behavior. According to this method, in multi-member households, each member has their own preferences, and what can be important between these members is the intra-household bargaining process. In this article, at first, we will give an introduction including the theoretical foundation and the background of the research, then, while introducing the unitary model as an introduction to collective models, we will examine the collective model and inta-household collective models. At the end, the contents are summarized and suggestions for future research are presented.

Livestock businesses have various risks of death that can occur due to accidents, natural disasters, and disease outbreaks. To anticipate the risks that occur, the government seeks to help farmers through agricultural insurance, including the cattle and buffalo business insurance program (AUTSK= Asuransi Usaha ternak Sapi/Kerbau). This study aims to analyze the implementation of the AUTSK program and the factors that affect the income of dairy farmers. The research was conducted in Ngajum District, Malang Regency with the consideration that this area is a center for dairy cows. Data were collected from 40 dairy farmers obtained by simple random sampling. Furthermore, the data was edited and compiled, and then analyzed using the multiple linear analysis method (which was transformed from Cobb Douglas function). The results showed that implementation of the AUTSK program in Malang Regency tended to be less attractive to farmers because the fulfillment of claims was not timely (the period of disbursement of funds was too long). Farmer education, livestock ownership and the cost of concentrate feed have a significant effect on the income of dairy farmers. Government needs to re-evaluate implementation of livestock insurance so that farmers can continue their business. Limitation of this study is difficulty of separating cost of production facilities for each cow, so that the expenditure for lactating cows is also difficult to calculate correctly.

In a world scale economy considering interlinkage and interactions between countries, economic shocks will affect various economies through channels. Meantime, the oil price is one of the most important channels. New studies show that the connection between the oil price and the world economy has numerous complications which could not be incorporated in traditional frames with only taking into consideration separated and identified oil supply and demand shocks without considering synchronicity and the source of the main shocks. Therefore it is essential to model a multi-dimensional system. The purpose of this study is to investigate the impact of oil price shocks on the major macroeconomic variables of oil-exporting countries from 1974Q1 to 2019Q4 using the global vector autoregressive (GVAR) approach. The macroeconomic variables include four domestic variables, three foreign variables and one global variable. In particular, it provides a theoretical framework for the global oil market to illustrate how multi-country approach to modeling oil markets can be used to identify country-specific oil price shocks. On the empirical side, it shows the global economic implications of oil price shocks vary considerably depending on which country is subject to the shock. The results of this study indicate that the economic consequences of a positive oil price shock are different on macroeconomic variables in oil-exporting countries in short-run and long-run. However, in response to a positive oil price shock, most of OPEC countries experience long-run inflationary pressures.

Efficient marketing will prosper the actors in each marketing agency, producers and consumers. Efficiency will be created if marketing costs can be minimized so that the percentage of producer prices to consumers is not too large, and there is no gap in the profit ratio to marketing costs between marketing agencies. The study aims to analyze marketing efficiency of tangerines and siamese in Gadingkulon Village. Data were collected from 87 citrus farmers who were selected by simple random sampling. Traders were determined by snowball sampling, consist of 17 collectors, 5 wholesalers, and 7 retailers were selected. Data were edited in the field, tabulated, compiled, then presented in tabular form, analyzed and described. The results showed that tangerines and siamese in Gadingkulon Village had an imperfect competitive market structure which was monopolistic. Marketing of the two types of oranges involves four channels i.e. collectors, retailers (inside and outside Malang Regency), and wholesalers. Oranges marketing system is not yet efficient, where wholesalers have larger profit margin ratio than other market players. Marketing channels I and II for tangerines are more efficient than channels III and IV. Meanwhile, marketing channel I for siamese is more efficient than channel II, III, and IV.

Oranges are favored by consumers, especially during pandemic covid-19, because they contain high vitamin C. Gadingkulon Village, located in Dau District, Indonesia, is one of the largest oranges producing villages. Mainstay plantation commodities of the village are tangerines and siamese. Agricultural commodities generally fluctuate in price and production. The study’s purpose was to evaluate feasibility of farming tangerines and siamese. Data were collected from 87 farmers who grow both types of oranges. Farmers were selected by simple random sampling, where the number is determined using slovin formula. The data were analyzed using investment criteria of revenue cost ratio, benefit cost ratio, break event point for price and production, payback period, net present value and internal rate of return. The results show that tangerine and siamese farming were feasible to develop because investment criteria number exceeds some criteria. Payback period is less than five years, price and production break event point were lower than that received by farmers, net present value is relatively large and positive, rate of return on capital is higher than social opportunity cost of capital. Oranges farming was feasible yet, even though prices have fallen by 10% and production by 30%. Siamese were more profitable than tangerines.

This has resulted in intervention in many time series related to Ukraine. For example, the time series of the daily exchange rates of Ukrainian Hryvnia (UAH) and United States Dollars (USD) experienced an intervention on the first day of Russian incursion. By Box and Tiao (1975) approach, a realization of the time series from 1 January 2022 to 15 March 2022 is analyzed. The intervention model arrived at is found adequate. It can be the basis for management and planning.

ICT has been considered a crucial player in environmental quality in the present age of industrial revolution and technological advancement. This study, therefore, seeks to examine the effects of ICT on environmental quality including technological innovation in selected Asian developing countries. A panel data that spanned from 1990 to 2018 is utilized to pursue the objectives of this study by applying second-generation panel approaches. In the long run, an inverted U-shaped relationship between the ICT index and CO2 emission is found by FEM and FMOLS estimators, indicating that environmental pollution decreases after attaining a threshold level of ICT development in selected Asian developing countries. The study reveals that technological innovation has a negative and significant influence on reducing CO2 emission, leading to energy efficiency and diminishing the intensity of energy used by inventing environmentally friendly technologies. Besides, electricity consumption and economic growth have positive and significant effects on the environment however, a negative and significant effect is found in the case of trade openness. The interactive effect of ICT and economic growth decreases the level of pollution while the moderate effect of ICT and technological innovation worsens the environmental quality in sample countries. The findings reveal that the role of ICT and technological innovation in mitigating environmental degradation still needs improvement in sample countries. The use of environmentally friendly ICT products and more green technological innovation are needed to improve energy efficiency by providing more fiscal incentives and infrastructures and enforcing environmental laws and regulations in the sample countries.
