Abstract: Using data from 85 NAICS 4 digit-level industry classifications that span the years 2004-2008, we evaluate whether productivity differentials, which have been shown to determine the decision of firms to export, affect the extensive margins of trade at the industry-level (i.e., the number of firms within an industry that engage in exporting). We use a stochastic frontier production function to derive a time-varying, industry-specific measure of technical efficiency. Employing a multi-level mixed effects model and accounting for the variance structure of the data (i.e., destination markets, industries, and time), we examine the average effect of an increase in industry-specific technical efficiency on the number of firms involved in exporting and the corresponding industry-specific deviations. Our results show that higher levels of industry-specific technical efficiency correspond with larger numbers of firms involved in exporting implying the importance of giving due consideration to approaches that focus on improving technical efficiency. Additionally, a much larger increase is observed among small-sized firms than for medium- or large-sized firms. We discuss the implications of the observed deviations, particularly for policy makers interested in increasing the extensive margins of their nations’ trade.

Description: The desire of firms to enhance their global presence, diversify their production and the interest of policymakers to augment domestic production with more efficient foreign technology has contributed to a surge in the cross border flow of capital. By taking into account market characteristics such as market maturity and export platform status of Japanese FDI hosts during the 1990s, this dissertation examines the link between FDI, trade and exchange rate volatility. More specifically, the following questions are addressed: What induces multinational firms to reach diverse destinations? Which of the host country characteristics attract investing firms most? Are trade flows among partners related to the volume of FDI flows between them? What does the geographical distribution of FDI reflect: efficiency, technological advances, or liberalization of trade and FDI policies? Given the diminishing role of the traditional FDI driving factors (such as factor abundance and cheap labor), to what extent do market maturity, export platform status and size of the host nations matter in determining the inflow of FDI?

Abstract: Using data from the 2006 Social Capital Community Survey in Duluth, Minnesota, and Superior, Wisconsin, USA, we investigate associations between individual social capital measures (attitudes on trust, formal group involvement, informal socializing, organized group interaction, social support and volunteer activity) and self-rated health after controlling for individual and economic characteristics. In particular, we address issues of social capital as an endogenous determinant of self-reported health using instrumental variables probit estimation. After accounting for the endogeneity of these various measures of individual social capital, we find that individual social capital is a significant predictor of self-rated health.

Abstract: Using data from the World and the European Values Surveys, we estimate cultural distances between the US and 54 immigrant home countries and examine the influence of cultural distance and immigrant populations on US-home country trade for the years 1997-2004. Our study indicates that the trade-enhancing effect of immigrants partially offsets the trade-inhibiting effect of cultural distance. Further, decomposing our measure of cultural distance and revisiting the immigrant-trade relationship, we find significant variation in the extent to which immigrants counter the trade-inhibiting influences of underlying dimensions of culture on imports and exports. Our findings have the implication that by countering the trade-inhibiting influences of cultural differences between their home and host countries, immigrants exert pro-development effects.

Abstract: Employing data for Italy and 68 trade partners that span the period 1996-2001, we examine the role of immigrants in influencing Italian exports to and imports from their respective home countries. Particular emphasis is placed on variation in the immigrant-trade relationship across Former Soviet Republic (FSR) and Post-Communist (PCOM) home country classifications relative to immigrants from non-FSR and non-PCOM home countries. The findings provide information that may assist in policy formulation and lead to more enlightened public and political debates of the issue. Immigrants are generally found to exert pro-trade influences; however, the typical immigrant from an FSR or PCOM home country exerts greater absolute influences on Italian-home country trade as compared to immigrants from non-FSR and non-PCOM home countries.

Abstract: Employing data for Italy and 68 trade partners that span the period 1996-2001, we examine the role of immigrants in influencing Italian exports to and imports from their respective home countries. Particular emphasis is placed on variation in the immigrant-trade relationship across Former Soviet Republic and Post-Communist country classifications relative to immigrants from non- and non- countries. The findings provide information that may assist in policy formulation and lead to more enlightened public and political debates of the issue. Immigrants are generally found to exert pro-trade influences, with proportional immigrant effects being somewhat comparable across home country classifications. However, estimated per-immigrant effects, in absolute terms, of immigrants from or countries are greater in magnitude as compared to the effects of immigrants from non- and non-countries.
2007. "Immigration Policy, Cultural Pluralism and Trade: Evidence from the White Australia Policy," Pacific Economic Review, 14(4):489-510. With Roger White, Franklin and Marshall College, Lancaster, PA
Abstract: We examine a potential immigrant-trade link for Australia using data for 101 trading partners that span the years 1991-2000. We report that immigrants from nations privy to preferential treatment under the White Australia policy have negligible effects on Australian trade. However, immigrants from nations that, historically, were not afforded preferences typically increase exports to and imports from their respective home countries by $1,887 and $865, respectively. This suggests immigration that increases cultural pluralism may positively influence trade. Immigrants increase trade in differentiated products to a greater extent than trade in homogenous products. Similarly, with respect to non-manufacturing products, immigrants tend to increase exports more than imports. However, when considering the influence of immigrants on trade in manufacturing products we see that imports increase more than exports.

Abstract: Using cross-section data on urban households from Jimma city, Southwestern Ethiopia, in this paper we apply the economic theory of consumer choice and examine some endogenous household characteristics that affect the demand for children among urban households in Ethiopia. Based on parameter estimates derived from a count data model, we also simulate the average number of children desired by a woman of median urban household characteristics and assess the extent to which an exogenously set population policy goal of lower fertility can be achieved. The results of our study indicate that enhancing paternal and maternal education, altering the economic value of children, increasing household income, and delaying the marriage age as important policy measures that should be pursued to reduce fertility. Institutional approaches that involve “faith-based initiatives” are also relevant. An important implication of the study is that by using measures that target these socio-economic variables via market incentives, fertility levels among urban households in Jimma and other urban areas of Ethiopia with similar demographic features can be reduced.
