Income inequality and FDI: evidence with Turkish data

This article explores how foreign direct investment (FDI) and other determinants impact income inequality in Turkey in the short- and long-run. We apply the nonlinear auto-regressive distributed lag (ARDL) modelling approach, which is suitable for small samples. The data for the study cover the years from 1970 to 2008. The empirical results indicate the existence of a co-integration relationship among the variables with asymmetric adjustment of the income distribution in the short- and long-run. The negative impact of FDI on the Gini coefficient, decreasing income inequality, is statistically significant in the short- and long-run, though with a quantitatively small impact in both cases. In the short run, GDP growth increases inequality initially, an effect that is reversed in the next period, increases in domestic gross capital formation decreases inequality, and increases in the literacy rate have very minor adverse effects on income equality. However, in the long run these variables have no statistically significant effects on the Gini coefficient. A reduction in the population growth rate reduces inequality in the short run but has no effect in the long run, whereas an increase in the rate reduces inequality in the long run but has no effect in the short run.     

Transboundary Pollution and the Welfare Effects of Technology Transfer

We examine the welfare effects of a transfer of pollution abatement technology in a two-country model. In each country, one industry discharges pollution as a byproduct of output, and the sum of domestic and cross-border pollution decreases the productivity of the other industry. We show the effects of technology transfer on the terms of trade, pollution levels, and welfare. Technology transfer decreases the pollution affecting each country under certain conditions. We derive and interpret the conditions under which technology transfer enriches the donor and the recipient. The results essentially depend on the trade pattern and the fraction of cross-border pollution.     

On Cost Benefit Rules for Green Taxes

This paper concerns the welfare effects of a green tax reform in a dynamic general equilibrium model with preexisting taxes on labor income and capital income. In comparison with previous studies on green taxes in dynamic models, which have focused their main attention on long run effects of such reforms, I derive cost benefit rules for a change in the tax mix by using the properties of the value function in optimal control theory. This enables me to relate the welfare effect of a change in the tax mix to responses in employment, the capital stock, (flow) emissions and the stock of pollution along the whole general equilibrium path. Another contribution of the paper is to examine under what conditions an emission tax, which is set permanently below the marginal damage of pollution, is welfare superior to an emission tax path that fully internalizes the external effect.     

Asymmetric impacts of ICT and energy intensity on agricultural productivity: Evidence from Asia-Pacific region

In the contemporary times of rising food insecurity and malnutrition, the agricultural sector needs more attention. This study aims to investigate the asymmetric impacts of information and communication technologies (ICTs), energy intensity, urbanization, and inequality on agricultural productivity for 20 Asia-Pacific countries from 1990 to 2020. To investigate asymmetric impacts, the study employs the panel nonlinear autoregressive distributed lag (NARDL) model. The estimated results revealed that positive and negative shocks in ICT, energy intensity, and urbanization have asymmetric impacts on agricultural productivity in the long run, whereas symmetry is observed in short-run impacts. It is found that a 1% increase (decrease) in ICT and urbanization increases (decreases) agricultural productivity by 0.292% (0.662%) and 2.717% (2.759%), respectively, whereas a 1% increase (decrease) in energy intensity decreases (increases) agricultural productivity by 0.252% (0.216%) in the long run. Furthermore, the results of the Dumitrescu-Hurlin panel causality test point out the existence of bi-directional causality between agricultural productivity and the independent variables (ICT, energy intensity, urbanization, and inequality). Based on the findings, the study suggests that the Asia-Pacific countries should increase the application of ICT and use energy more efficiently in agriculture to boost agricultural productivity.     

Taxation, Bequests, and Short and Long Run Timber Supplies: An Overlapping Generations Problem

This paper uses an overlapping generations model with one-sided altruism to study the effects of several forest taxes that target bequests and affect timber supply. Unlike previous work, we investigate bequests and timber supply in both the short and long run when bequests are costly (e.g., taxed). The landowner's problem is examined in the short run, while the government's problem is examined in the long run assuming the existence of a steady state. We also consider taxes targeting harvests, growth, savings and bequests. Several new results are established concerning the interactions of taxes that might be used by a government to alter short and long run forest capital stocks: (i) the presence of a forest bequest tax affects the neutrality of harvest tax in both the short and long run, (ii) in the long run the bequest tax decreases bequests and timber supplies. When the bequest tax is not present, the capital income tax is neutral with respect to bequest and timber supply, while the harvest tax is neutral only if forest productivity is also not taxed. Finally, (iii) in the short run, the substitution and total effects of taxes in landowner decisions generally depend on the presence of the bequest tax. The results have implications for Pigouvian tax design and second best tax choice.     

A Model of Educational Investment,Social Concerns,and Inequality

We consider a model in which educational investments entail productivity gains, signaling power, and social status. The latter depends on the agent's relative achievement in one of three dimensions: innate skills, level of schooling, and income. We study the three scenarios separately and characterize the conditions under which social concerns increase or decrease educational and income inequality. Inequality increases (decreases) if education lowers the stigma suffered by low‐skilled workers less (more) than it boosts the prestige enjoyed by high‐skilled workers. We discuss the expected results of some policies in light of these findings.     

Foreign direct investment,international trade,and firm heterogeneity

We present an asymmetric model with firm heterogeneity and foreign direct investment (FDI) from a developed country to a developing country. We found that the successful entry firms could be sorted from highest to lowest according to productivity as reimport firms, FDI firms, export firms, and domestic firms. We also found that FDI decreases (increases) the gross national income of the developed (developing) country, but it can either increase or decrease the world income according to the level of the relative propensity to spend. In addition, we demonstrated that FDI influences welfare through variations in average price, national income, and the number of types of goods.     

Effects of Aspirations and Habits on the Distribution of Wealth

We analyze how the introduction of habits and aspirations affects the distribution of wealth when the labor productivity of individuals is subject to idiosyncratic shocks and when bequests arise from a joy‐of‐giving motive. In the presence of either bequests or aspirations, labor income shocks are transmitted intergenerationally, and this transmission, together with contemporaneous shocks, determines the distribution of wealth. We show that the introduction of aspirations (habits) decreases (increases) the average wealth, and increases (decreases) both its intragenerational variability and the degree of intergenerational mobility. Therefore, a distinction between aspirations and habits is relevant because they involve different implications for the distribution of wealth.     

Rigid labour markets with trade and capital mobility: theory and evidence

Abstract We develop a multi‐country model with imperfect labour markets to study the effect of labour market frictions on bilateral trade flows. We use a framework that allows for goods trade and capital mobility and show that labour market imperfections exert opposite effects in the absence of capital mobility (the short run) and its presence (the long run), respectively. In the short run, a higher degree of labour market rigidity decreases the value of total trade, but increases the share of intra‐industry trade for a country that is larger than its trading partner. The reverse effects are observed when capital is allowed to cross country borders. Using data on unemployment and income distribution for 23 OECD countries, we compute the central parameter in our theoretical model that describes the degree of labour market rigidity. We use this new empirical concept to provide evidence for our theoretical findings by means of reduced‐form regressions as well as simulation results of a calibrated general equilibrium model.     

Environmental capital flight and pollution tax

This paper analyzes the impacts of a production pollution tax on environmental capital flight and national product in a two-country static general equilibrium model with two-way foreign investment. It is assumed that the capital input in both countries is a composite good of domestic and imported capital. And pollution is assumed to originate in the production process. The productivity of capital in each country is negatively (or positively) related to the worldwide aggregate emissions.The analysis shows that when a domestic pollution tax is levied, domestic capital outflows increase and foreign capital inflows decrease for sufficiently high elasticities of substitution between labor (immobile input) and capital (mobile input) in both countries. Moreover, with negative transnational externalities, increases of a domestic pollution tax reduce domestic production and increase foreign production. The difficulty of substitution between immobile and mobile inputs hinders the optimal allocation of worldwide capital and national product. In this paper, the optimal pollution tax is based on global welfare maximization, not on global income maximization, taking into consideration the impact of income change on individual welfare. Therefore, an optimal pollution tax in the developing country should be lower for a given rate of pollution.     

Wage Inequality,Increased Competition,and Trade Liberalization: Short Run vs Long Run

This paper examines the impact of increased competition and trade liberalization on skilled–unskilled wage inequality in the short run as well as the long run. It is shown that an increase in the number of firms in the producer services sector increases wage inequality in the short run even if the income shares of capital in the industrial and agricultural sectors were identical. A decrease in the services sector's fixed cost decreases wage inequality in the short run if the income share of capital in the agricultural sector is relatively large. Owing to the presence of external economies, a decrease in the services sector's fixed cost increases wage inequality in the long run. A decrease in import duty on the agricultural good increases wage inequality in the short as well as the long run but its effect in the long run is stronger due to the presence of external economies in the industrial sector.     

Growth Effects of Capital Income Taxes: How Much Does Endogenous Innovation Matter?

The paper compares the way economies with exogenous and endogenous innovation respond to capital income taxes. If innovation is exogenous, tax cuts increase saving. If innovation is endogenous, tax cuts increase innovation as well. Faster innovation raises capital productivity and calls forth still more saving. A larger capital stock lowers the discount rate, increases the present value of monopoly profit and calls for faster innovation. How large a difference endogenous innovation might make is an open question. We calculate numerical solutions of a model including features of the U.S. tax code that affect incentives to innovate. The results suggest that models with exogenous innovation substantially underestimate long–run effects of capital income taxes.     

Trade and Global Pollution in Dynamic Oligopoly with Corporate Environmentalism

This paper examines the effects of international trade in the presence of dynamic oligopolistic competition where the stock of global pollution has a negative welfare effect and the oligopolists' objectives may include society's pollution damage as well as private profits. In a symmetric case where the number of firms, emission coefficient, and firms' environmental consciousness are the same in two countries, an opening of trade unambiguously improves each country's welfare in the short run. In the long run, however, trade increases the stock of global pollution and hence, whether opening of trade is beneficial depends on the parameters of the economy. If there are asymmetries between countries, the short‐run gains from trade in both countries are not necessarily guaranteed, because trade liberalization may increase output in one country and reduce it in the other. Moreover, free trade may result in lower pollution stock than under autarky.     

A SAM-CGE Demonstration Model for Indonesia: Static and Dynamic Specifications and Experiments

In this article it will be demonstrated how a simple static Computable General Equilibrium model of the Indonesian economy can be constructed using the Social Accounting Matrix as a database. It will be shown that under a few assumptions the constant labour force and capital stock in the static model can be elaborated to dynamic specifications. In both static and dynamic versions the effects of productivity increases are investigated, leading to the conclusion that with respect to income and employment generating effects innovating sectors are worse off than non-innovating sectors due to low elasticities of demand.

The impact of earnings management on the performance of ASEAN banks

Southeast Asian financial liberalization policies have enthused both performance evaluation (a pro) and earnings management (a con). Using a sample of ASEAN commercial banks for the period 2007–2014, this study decomposes their banking performance into managerial and profitability efficiencies. An efficiency analysis reveals that Singaporean banks obtained the highest overall and profitability efficiencies, while Bruneian banks had the lowest rates of banking performance. In the stage of managerial efficiency, the most inefficient banks are those of the Philippines, whereas the greatest level is related to Malaysian banks. A frontier projection analysis suggests that Singaporean banks and Malaysian banks are generally more efficient in managing their expenditures and long-term assets in generating income in the long run. With respect to the con, a regression analysis indicates that loan loss provisions are negatively related to banking performance. Overall, it is advisable that policy makers with oversight function should promote performance evaluation from a multidimensional perspective, and keep an eye on estimates of loan loss provisions at banks over years because increases/decreases in loan loss provisions mean decreases/increases in net income or return on assets.     

Does trade liberalization increase global pollution?

In this paper we consider a simple duopoly market in which a home firm and a foreign firm use labor to produce an identical product and supply it to the home market. Firms emit pollution as a by-product of production. We show conditions under which international trade liberalization decreases (increases) the global pollution.     

Growth effects of environmental policy when pollution affects health

In this paper, we develop a R&D-based growth model with a pollution externality and a health production sector. We study how health-impairing pollution affects long term growth, and the effect of an emissions' reduction policy (tax). We show that a tighter environmental tax has positive effects on growth via two channels. On the one hand, it improves workers' health and, thereby, productivity; on the other hand, it induces a reallocation of resources towards R&D and, thereby, higher research intensity. The size of the growth effect of a tighter environmental tax, and the level of the optimal environmental tax, are both positively correlated with the weight individuals place on health relative to consumption. As for welfare, a tighter environmental tax brings about utility gains in the long run and, potentially, also in the short run.     

The growth effects of tax rates in the OECD

This paper explores the merits of macro‐ and micro‐based tax rate measures within an open economy “fiscal policy and growth” model. Using annual data for 15 OECD countries we find statistically small, non‐robust long‐run growth effects of macro‐based average tax rates on capital income and consumption, but some evidence for average labour income tax effects. Changes in “micro” marginal income tax rates at both the personal and corporate levels yield statistically robust GDP responses of modest size. Both domestic and foreign corporate taxes appear relevant. In general, tax effects on GDP operate largely via factor productivity rather than factor accumulation.     

Willingness to pay to control PM2.5 pollution in Jing-Jin-Ji Region,China

This letter aims to study individual willingness to pay (WTP) to mitigate PM_2.5 pollution in the Jing-Jin-Ji region by using contingent valuation method. Our survey indicated that residents in this region were highly concerned about PM_2.5 pollution control and supported PM_2.5 pollution control policies. In this study, a payment card (PC) format is used to elicit residents’ perceived WTP. With a two-part model, we estimate the mean WTP for an 80% reduction of severe PM_2.5 polluting days in this region is 602 CNY a year, approximately accounts for 1% of the GDP per capita. This result indicates an important funding source for the government to control PM_2.5 pollution in the region. In the econometric analysis, the mean WTP is found to significantly relate with income, expense, age and education level. It decreases with income, age and educational level, but increases with expense, and it is higher for females, people who have children, own cars and apartments but lower for those having larger families. By comparing with relevant researches, this letter indicates a strong and ever-increasing WTP for air pollution control among residents in the Jing-Jin-Ji region, China.     

Why did US air pollution decline after 1970?

US economic growth and air pollution were decoupled after 1970. Possible explanations include regulation, oil price shocks, technology and income growth. This paper uses VAR analysis to show that the 1970 Clean Air Act (CAA) may have actually increased pollution in the short run but led to accelerated improvements in abatement technology. Gross domestic product and consumption growth had little direct effect while oil price increases caused small but significant emissions reductions. Recursive simulation shows that overall, the CAA, by accelerating improvements in abatement technology, reduced total emissions as of 1998 to 46% of what they would have been.
