Factor Taxation, Income Distribution and Capital Market Integration

This paper addresses the optimal mix of capital and wage taxation when policymakers maximize the political support of workers and capitalists, subject to a fixed revenue requirement. Capital market integration increases the efficiency costs of a tax on capital but simultaneously changes the political equilibrium through its effect on the distribution of factor incomes. These distributional effects are directly opposed in the capital importing and the capital exporting region. While the capital tax rate will always be lowered in the capital importing region, the tax rate in the exporting country will rise when political resistance to market-induced changes in the distribution of income is sufficiently high.     

Capital Controls: a Political Economy Approach

The paper examines the economic consequences of political conflicts that arise when countries implement capital controls. In an overlapping‐generations model, agents vote on whether to open or close an economy to capital flows. The young (workers) receive income only from wages while the old (capitalists) receive income only from savings. The authors characterize the set of stationary equilibria for an infinite‐horizon game. Assuming dynamic efficiency, when the median representative is a worker (capitalist), capital‐importing countries will open (close) while capital‐exporting countries will close (open). These predicted patterns are consistent with data on liberalization policies over time and across various countries.     

On the International Linkages between Trade and Merger Policies*

In a three‐country model, this paper investigates linkages between merger incentives of exporting firms and the trade policy of an importing country. When exporting firms come from only one country, the tariff response of the importing country reverses the welfare effects of a merger in the exporting country. If there exist two exporting countries, a merger creates two types of conflicting international externalities. First, a merger in one exporting country increases profits of all firms. Secondly, non‐merged firms lose if the importing country is free to raise its tariff in response to a merger of foreign exporters.     

Life expectancy and economic development: Evidence from microdata

This study examines the effect of life expectancy on fertility, education, and labor force participation. Using birth and sibling histories from the Demographic Health Surveys conducted in sub‐Saharan Africa, I construct a time series of age‐specific birth rates and mortality rates at the country‐region level. I use these data to test the implications of a general equilibrium model linking life expectancy to fertility, human capital, and labor supply. My results suggest that increases in life expectancy reduce fertility, increase education, and increase labor force participation. Overall, my empirical results suggest that in sub‐Saharan Africa, increases in life expectancy will have a positive impact on growth through fertility, education, and labor supply but that the effect will be small. My results also rule out the possibility that recent shocks to adult mortality in high HIV prevalence countries will reduce fertility, increase labor productivity, and lead to faster growth.     

Export cartel and consumer welfare

The purpose of this paper is to show that export cartels are not necessarily harmful for consumers in the importing countries. Using a strategic trade policy model, we show that, contrary to the harmful effect, product‐market cooperation benefits consumers by affecting the trade policies. We further show that consumers in the importing countries are affected adversely if cooperation is among the governments of the exporting countries, instead of the exporting firms.     

Having It All? Employment,Earnings, and Children*

We study the effect of family policies on female employment, fertility, and the gender wage gap. We develop a life‐cycle model of heterogeneous households featuring endogenous labor supply, human capital accumulation, fertility, and home production. Our results suggest that human capital accumulation is important in accounting for the widening of the gender wage gap following children. We find that, in aggregate, childcare subsidies promote maternal employment and fertility, although the effects are heterogeneous across couples. A subsidy on home goods increases female employment, but primarily later in life. Thus, it does not dampen the widening of the gender gap.     

Uniform Versus Discriminatory Tariffs

We analyze the non‐cooperative interaction between two exporting countries producing differentiated products and one importing country when governments use optimal policies to maximize welfare. The analysis includes product differentiation, asymmetric costs, and Bertrand competition. For identical exporting countries we demonstrate that the importing country always prefers a uniform tariff regime while both exporting countries prefer a discriminatory tariff regime for any degree of product differentiation. If countries are asymmetric in terms of production cost then the higher‐cost exporter always prefers the discriminatory regime but the lower‐cost exporter prefers the uniform regime if there is a significant cost differential. With cost asymmetry the announcement of a uniform tariff regime by the importer is not a credible strategy since there is an incentive to deviate to discrimination. This implies an international body can play a role in ensuring that tariff agreements are respected.     

Revisiting the oil price and stock market nexus: A nonlinear Panel ARDL approach

In this paper, we re-examine the relationship between oil price and stock prices in oil exporting and oil importing countries in the following distinct ways. First, we account for possible nonlinearities in the relationship in order to quantify the asymmetric response of stock prices of these two categories to positive and negative oil price changes. Secondly, in order to capture within group differences, we allow for heterogeneity effect in the cross-sections by formulating a nonlinear Panel ARDL model which is the panel data representation of the Shin et al. (2014) model and also analogous to the non-stationary heterogenous panel data model. Thirdly, we evaluate the relative predictability of the linear (symmetric) and nonlinear (asymmetric) Panel ARDL models using the Campbell and Thompson (2008) test. Our results depict that stock prices of both oil exporting and oil importing groups respond asymmetrically to changes in oil price although the response is stronger in the latter than the former. This finding is further corroborated by the out-of-sample forecast results suggesting that the inclusion of positive and negative oil price changes in the predictive model for stock prices will produce better forecast results only for the oil importing countries. Our results are robust to different oil price proxies, lag structure and in-sample periods. Overall, the dichotomy between oil exporting and oil importing countries has implications on oil price-stock nexus.     

Does international openness affect the productivity of local firms?

This paper examines how international openness can change firm productivity in south‐eastern Europe (SEE), a crucial question for middle‐income countries. Using firm‐level data for six transition economies over the 1995–2002 period, we identify whether foreign ownership and propensity to trade with more advanced countries can bring about higher learning effects. We find that: (i) foreign ownership has helped restructure and enhance the productivity of local firms in four out of six countries; (ii) exporting to advanced markets has a larger impact on productivity growth in four countries, especially when the firm's absorptive capacity is taken into account; (iii) in contrast, exporting to the less competitive markets of the former Yugoslavia seems to negatively affect productivity growth in three countries; and (iv) learning effects from importing are similar to those from exporting. Our results suggest that trade liberalization is not uniformly beneficial. Regional composition of trade flows and absorptive capacity of local firms matter. Thus, trade liberalization within the SEE region may not provide a substitute for a general trade liberalization which includes access to the more competitive markets of countries belonging to the Organization for Economic Co‐operation and Development.     

Fertility Decisions and Gender Differences in Labor Turnover, Employment, and Wages

A striking observation of the U.S. and other labor markets is the weak position of women in terms of job attachment, employment, and earnings relative to men. We develop a model of fertility and labor market decisions to study the impact of fertility on gender differences in labor turnover, employment, and wages. In our framework, individuals search for jobs and accumulate general (experience) and specific (tenure) human capital when they work. They can also increase their wage by moving to a job of higher quality. Labor market decisions (e.g., job acceptance and job mobility) may differ across genders: females that give birth may decide to interrupt their labor market attachment in order to enjoy the value of staying at home with their children. The model economy is successfully calibrated to match aggregate statistics in terms of fertility, employment, and wages. We find that fertility decisions generate important gender differences in turnover rates, with long lasting effects in employment and wages. These differences in labor turnover account for almost all the U.S. gender wage gap that is attributed to labor market experience by Blau and Kahn (2000, Journal of Labor Economics15(1), 1–42). The model also implies a very small role of tenure capital in accounting for wage differences between males and females (gender gap), and between females with and without children (family gap).

“十二五”时期我国对外贸易的转变

"十二五"规划实施时期,国际国内的新形势对我国对外贸易提出了新的要求。为了实现协调和持续发展,对外贸易必须实现一系列的转变:由注重出口规模增长转向进出口并重;由以发达国家为主要贸易对象转向贸易对象的多元化;由以货物贸易为主转向货物贸易和服务贸易并重;由单一地打破贸易保护转变为通过多种方式减少贸易摩擦。     

GLOBALIZATION,GENDER, AND GROWTH

We consider the effect of globalization on fertility, human capital, and growth. We view globalization as creating market opportunities for employment in less developed countries. We construct a specific model of household decision making, drawing on empirical observations in the development economics literature, and show that if the market opportunities produced by globalization are for women, then globalization reduces fertility and increases human capital formation. If the opportunities are for men, then fertility increases and human capital formation falls. We then show that globalization that produces job opportunities for women increases growth and produces a long run steady state with higher per capita consumption than would prevail either without globalization, or with globalization that creates jobs only for men.     

Trade liberalization,forward‐looking firms,and welfare

We set up an oligopolistic model with two exporting firms selling to a third market to investigate the welfare implications of trade liberalization when the exporting firms are forward‐looking. The results show that with cost asymmetry trade liberalization encourages the exporting firms to engage in tacit collusion, which may not only be detrimental to the domestic welfare, but also to the consumer surplus of the importing country. Moreover, we find that tacit collusion is less sustainable if the government of the importing country imposes a lower (higher) tariff on the more (less) efficient exporting firm. If a nonforward‐looking or a forward‐looking cost‐efficient domestic firm exists in the importing country, then trade liberalization also encourages tacit collusion.     

Gender Inequality and Trade*

The paper empirically explores the international linkages between gender inequality and trade flows of a sample of 92 developed and developing countries. The focus is on comparative advantage in labor‐intensive manufactured goods. The results indicate that gender wage inequality is positively associated with comparative advantage in labor‐intensive goods, i.e. countries with a larger gender wage gap have higher exports of these goods. Also, gender inequality in labor force activity rates and educational attainment rates are negatively linked with comparative advantage in labor‐intensive commodities.     

Increasing dispersion of skills and rising earnings inequality

In recent decades many countries have simultaneously liberalized their trading regimes and expanded their education systems. The theoretical effect of these regime shifts on the wage differential between skilled and unskilled workers is ambiguous. On the one hand, openness to trade causes demand shifts in the labor market which may widen or narrow the differential. This result depends on whether the unskilled wage is depressed, as in the case of importing countries, or raised, as in the case of exporting countries. On the other hand, an increased supply of more educated workers reduces their wages and narrows the skill wage gap. In this study of the labor market of Hong Kong, we document that recent changes in response to the trade liberalization of Mainland China and expanded access to education have increased the earnings differential between skilled and unskilled workers. Using detailed census data, we argue that the main reason for this outcome is the widened dispersion of skills across the earnings distribution, resulting from demand and supply shifts in the labor market caused by trade openness and expanded access to higher education.     

Endogenous Timing in a Strategic Trade Policy Game: A Two-Country Oligopoly Model with Multiple Firms

This paper examines strategic trade policy games where the number of firms in the importing and exporting countries differs and all firms play as Cournot oligopolies. Under the assumption of linear demand and constant marginal cost, we show that, if the number of firms in the exporting country exceeds that in the importing country by more than three, the government of the exporting country chooses to move as a leader, imposing an export tax on firms. The government of the importing country then becomes a follower and imposes an import tariff. This lies contrary to the previous study, which assumed that there is only one firm in each country.     

The Relationship Between Growth,Total Investment and Inward FDI: Evidence from Time Series Data

This paper explores the causal relationship between growth, total investment and inward FDI in 47 countries. Using error‐correction model, the significance, direction and sign of long‐run and short‐run causal effects between GDP, capital stock and FDI stock are investigated. The miscellaneous results echo the divergent theoretical viewpoints and the mixed empirical results of previous works. However, the evidence found in this study suggests that there are differences in growth mechanism between developed and developing countries, between various developing regions, and between oil‐exporting and non‐oil‐exporting countries. The main policy implication is that capital investment is essential for growth while FDI’s effect is uncertain in developing countries. FDI as well as total investment enhances growth only under some conditions.     

Strategic Regulation Policy in the Internet

Some countries are importers while others are exporters of global backbone connectivity. At the same time, input components such as local access are non-traded. This paper analyzes a non-cooperative regulatory game between importing and exporting countries, assuming that the prices of both traded and non-traded inputs can be regulated. We show that exporting countries choose a more restrictive regulation of non-traded goods than importing countries do. We further show that a requirement of international non-discrimination may hurt importing countries, and give firms producing traded inputs incentives to invest in quality degradation.     

Exporting and labour demand: Micro‐level evidence from Germany

It is widely believed that globalization increases the extent of employment and wage responses to economic shocks. In this paper, we investigate the effect of firms’ exporting activities on the wage elasticity of labour demand. Using rich, administrative linked employer–employee panel data from Germany and destination‐specific industry‐level information on trade flows, we explicitly control for self‐selection into exporting and endogeneity concerns. Overall, we find that exporting has a significant positive effect on the (absolute value of the) unconditional wage elasticity of labour demand. In line with our hypothesis, we further show that the effect is particularly strong for those plants that export a significant share of their output to low‐ and medium‐income countries, hence face relatively more price‐elastic product demand.     

Two Tales on the Returns to Education: The Impact of Trade on Wages

This paper uses micro data from the Current Population Survey combined with data from the US International Trade Commission and Bureau of Economic Analysis to evaluate the impacts of international trade (import penetration and export intensiveness) on wages with a special focus on the returns to education. Consistent with the literature, our empirical analysis provides evidence that the wage rates of similarly skilled workers differ across net‐exporting, net‐importing, and nontradable industries. Our results add to the literature by showing that the wage gap usually found across importing and exporting industries vanishes for highly skilled workers (workers with college degree and beyond) when we control for the cross‐effect between international trade and education, but the wage gap due to international trade still persists for low‐skilled workers. This finding supports the view that education serves as an equalizer and counterbalances the adverse impact from import penetration on wages of highly skilled workers.
