Optimal export taxes in a multicountry framework

This paper extends the optimum export tax analysis to multicountry partial (PE) and general equilibrium (GE) frameworks, using a computable general equilibrium (CGE) model of the global cocoa market. Analyzing myopic optimum, Nash optimum and Nash revenue maximizing taxes, we show that optimum and revenue maximizing taxes obtained in the GE framework differ from their PE counterparts, as they are determined not only by the elasticity of the residual demand curve facing the country, but by domestic supply conditions as well. Second, not only are Nash revenue maximizing taxes higher than Nash optimum taxes in the GE, but, paradoxically, the society attains a higher level of welfare under Nash revenue maximizing taxes than under Nash optimum taxes. Finally, we show that the frequent use of Lerner symmetry [Lerner, A.P., 1936. The symmetry between import and export taxes. Economica 11, 306–313.] in the policy-oriented analysis of optimum export taxes is not warranted.     

Heterogeneous effect of ethnic networks on international trade of Thailand: The role of family ties and ethnic diversity

Ethnic networks have been found to have a pro-trade effect in previous research. However, the heterogeneous effect of different ethnicities is under-studied. Drawing on the literature on social structure, this paper attempts to untangle the heterogeneous effect of ethnic networks on international trade using trade data of Thailand. We found that ethnic networks have a positive impact overall on trade, confirming the results of previous studies. However, the magnitude of the positive effect varies across different ethnicities along two dimensions. First, the strength of family ties in the culture of origin accelerates the pro-trade effect of its ethnic networks, suggesting ethnicities with stronger family ties have a cultural preference for trading within their own ethnic community. In comparison, ethnic diversity weakens the positive effect of ethnic networks on trade, suggesting an informational value of diverse ethnic structure in promoting trade between different ethnicities. Our study contributes new evidence of the enduring influence of social and cultural attributes on economic activities.     

Natural gas prices and stock prices: Evidence from EU-15 countries

This study investigates the long-run relationship between natural gas prices and stock prices by using the Johansen and Juselius cointegration test and error–correction based Granger causality models for the EU-15 countries. We employ quarterly data covering the period from 1990:1 to 2008:1. Empirical findings suggest that there is a unique long-term equilibrium relationship between natural gas prices, industrial production and stock prices in Austria, Denmark, Finland, Germany and Luxembourg. However, no relationship is found between these variables in the other ten EU-15 countries. Although we detect a significant long-run relationship between stock prices and natural gas prices, Granger causality test results imply an indirect Granger causal relationship between these two variables. In addition, we investigate the Granger causal relationship between stock returns, industrial production growth and natural gas price increase for Austria, Denmark, Finland, Germany and Luxembourg. As a result, increase in natural gas prices seem to impact industrial production growth at the first place. In turn, industrial production growth appears to affect stock returns.     

Productivity response to reduction in trade barriers: evidence from Turkish manufacturing plants

We examine the effects of trade policy changes on the evolution of productivity in the Turkish manufacturing industry. Plant level productivities are estimated for the 1983–1996 period following the procedure of Olley and Pakes. Industry averages indicate that productivity gains are largest in import-competing industries with highest gains reaching 8% per year during periods of rapid decline in protection rates. We find that productivity improvements resulting from declining protection rates are statistically significant and economically important, especially in import-competing sectors. More importantly, productivity improvements due to declining protection rates increase with the plant size.

Imported Machinery for Export Competitiveness

This article analyzes the relationship between export competitivenessand investment in machinery, allowing for imperfect substitutionbetween domestically produced and imported machinery. A translogexport price function is estimated for developed, exportorienteddeveloping, and import-substituting developing economies ina panel data setting. Between 1967 and 1990 imported machineryhelped lower export prices for export-oriented developing economies.Moreover, throughout the period imported machinery was not asubstitute for domestic machinery. Import-substituting developingeconomies were unable to harness imported machinery to reducecosts early in the period, but from about the early 1980s, withthe opening of their trade regimes, they were able to benefitfrom the cost-reducing effect. The results imply that innovativeeffort based on imported technologies can be a precursor tothe development of domestic innovation capabilities.     

Trading on Private Information: Evidence from Members of Congress

I examine the stock trades of members of Congress and find that over 2004–2010 the buy‐minus‐sell portfolios of powerful Republicans have the highest abnormal returns, exceeding 35% on an annual basis under a one‐week holding period. Among powerful Republicans, the abnormal returns are mostly concentrated in the portfolios of those with less trading experience. I also find that the positive abnormal returns disappear after the Stop Trading on Congressional Knowledge (STOCK) Act was passed in 2012. My results imply that the STOCK Act affected politicians' incentives to trade on private information, which they acquired through their power and party membership.     

Brand Equity and Firm Risk: An Empirical Investigation in an Emerging Market

The aim of this article is to investigate the relationship between brand equity and firm risk in Turkey using a sample of 254 firm-year observations for the period 2009–2014. Our findings suggest that brand equity is an important determinant of equity risk in addition to conventional firm-specific variables. In particular, after controlling for firm-specific variables, the results reveal that firms with high brand equity experience lower volatility in stock returns. We also find that enhancing brand equity is an important tool for firms in reducing unsystematic and downside systematic risk in their stock prices. Our findings are robust to different valuation models of domestic and global investors as well as different methods of estimations. The results are encouraging for both marketing managers and investors, particularly those in emerging markets where stock price volatility is relatively higher than in developed markets.     

Redistribution through education and other transfer mechanisms

Educational subsidies are frequently justified as a method of altering the income distribution. It is thus natural to compare education to other tax-transfer schemes designed to achieve distributional objectives. While equity-efficiency trade-offs are frequently discussed, they are rarely explicitly treated. This paper creates a general equilibrium model of school attendance, labor supply, wage determination, and aggregate production, which is used to compare alternative redistribution devices in terms of both deadweight loss and distributional outcomes. A wage subsidy generally dominates tuition subsidies across a wide range of fundamental parameters for the economy. Both are generally superior to a negative income tax. With externalities in production, however, there is an unambiguous role for governmental subsidy of education, because it both raises GDP and creates a more equal income distribution.     

Costly Pre‐Play Communication and Coordination in Stag‐Hunt Games

In this paper, we experimentally investigate the impact of costly indirect and direct messages on coordination levels in a stag‐hunt game. Three main insights emerge from our experiments. First, we find a significant decrease in message usage with message cost in both treatments and a higher decrease in the indirect‐message treatment. Second, we find that although there is no significant effect of costless or costly indirect messages on the frequency of risky actions, both costless, and costly direct messages significantly increase the frequency of risky actions. Third, while we find a significant increase in the coordination rate on the payoff‐dominant equilibrium from costless indirect message treatment to costly indirect message treatment, this rate significantly decreases from costless direct message to costly direct message treatment. Our findings show that depending on the structure of messages, message cost may increase or decrease the coordination rates on the payoff‐dominant equilibrium with respect to costless communication. However, costly communication increases efficient coordination rates with respect to the no communication baseline. Copyright © 2016 John Wiley & Sons, Ltd.
