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.     

Better to give than to receive: Predictive directional measurement of volatility spillovers

Using a generalized vector autoregressive framework in which forecast-error variance decompositions are invariant to the variable ordering, we propose measures of both the total and directional volatility spillovers. We use our methods to characterize daily volatility spillovers across US stock, bond, foreign exchange and commodities markets, from January 1999 to January 2010. We show that despite significant volatility fluctuations in all four markets during the sample, cross-market volatility spillovers were quite limited until the global financial crisis, which began in 2007. As the crisis intensified, so too did the volatility spillovers, with particularly important spillovers from the stock market to other markets taking place after the collapse of the Lehman Brothers in September 2008.     

Public housing units vs. housing vouchers: Accessibility,local public goods,and welfare

We develop a general equilibrium model of residential choice and study the effects of two housing aid policies, public housing units and housing vouchers. Land is differentiated by both residential accessibility and local public goods, and the provision levels of local public goods are determined by property tax revenues and neighborhood compositions. Households differ in their incomes and preferences for local public goods. Housing aid policies are financed by general income taxes. We discuss how the location of public housing units is a fundamental policy variable, in addition to the numbers and sizes of units, and argue that vouchers not only cause less distortion for social welfare compared to public housing, but may also improve overall welfare.     

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.     

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.     

A momentum trading strategy based on the low frequency component of the exchange rate

In this paper, we develop a momentum trading strategy based on the low frequency trend component of the spot exchange rate. Using kernel regression and the high-pass filter of Hodrick and Prescott [Hodrick, R., Prescott, E., 1997. Post-war US business cycles: An empirical investigation. Journal of Money, Credit and Banking 29, 1–16], we recover the non-linear trend in the monthly exchange rate and use short-term momentum in this to generate buy and sell signals. The low frequency momentum trading strategy offers greater directional accuracy, higher returns and Sharpe ratios, lower maximum drawdown and less frequent trading than traditional moving average rules. Moreover, unlike traditional moving average rules, the performance of the low frequency momentum trading strategy is relatively robust across different time periods. The low frequency momentum trading strategy is also robust to the choice of smoothing parameter (in the case of the HP filter) and the distribution and bandwidth parameter (in the case of kernel regression) over a wide range of values.     

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.
