Trade,Diaspora and Migration to New Zealand

This paper examines the hypotheses that a greater stock of migrants in New Zealand from a particular country leads to more trade between that country and New Zealand, and a greater stock of New Zealanders living overseas in a particular country leads to more trade between that country and New Zealand. It also examines the relationships between migration, diaspora and tourism exports. The literature suggests that migrants can stimulate trade by lowering transaction costs, and by bringing with them preferences for goods produced in their home country. Our approach is to apply panel data techniques, within the framework of a standard gravity model of trade, to a dataset consisting of information on 233 countries in each of the 26 years between 1981 and 2006. We estimate a random effects panel sample selection model using correlated random effects. Our results indicate that migration does indeed stimulate trade. In our benchmark specification, merchandise exports from and imports to New Zealand both have a statistically significant relationship with numbers of migrants in New Zealand; imports also have a statistically significant relationship with numbers of New Zealanders overseas. Our results also suggest that migration stimulates imports more than exports.     

Bayesian analysis of the ordered probit model with endogenous selection

This paper presents a Bayesian analysis of an ordered probit model with endogenous selection. The model can be applied when analyzing ordered outcomes that depend on endogenous covariates that are discrete choice indicators modeled by a multinomial probit model. The model is illustrated by analyzing the effects of different types of medical insurance plans on the level of hospital utilization, allowing for potential endogeneity of insurance status. The estimation is performed using the Markov chain Monte Carlo (MCMC) methods to approximate the posterior distribution of the parameters in the model.     

Financial market participation and the developing country business cycle

I explore the implications of limited participation in financial markets on a standard small open economy business cycle model. Despite its parsimony, the limited participation model developed in this paper improves over the standard model in terms of explaining two important features of business cycle facts of developing countries: high volatility of consumption, and high negative correlation between the trade balance and output. Limited participation model is then used to inspect the effects of financial development and integration on macroeconomic volatility. Under a standard calibration, limited participation model leads to the conclusion that financial development and integration are associated with higher investment and output volatility. Effect of more participation on consumption volatility is dependent on the specification of the risk premium function.     

Sea turtle interactions with Hawaii's longline fishery: an extended multi-objective programming model incorporating spatial and seasonal dimensions

The numerous discussions regarding the advantages and disadvantages of Turkey's becoming a member of the Customs Union has been inconclusive. The empirical analysis that mostly focus on the changes in the volume of trade without much regard to the conjectural changes have also been insufficient. This study attempts to shed light on this issue in a formal analysis of Turkey's international trade by empirically accounting for the changes before and after the Customs Union Agreement (CUA). In doing so, we explicitly account for the concurrent changes in the macroeconomic environment that may have affected Turkey's trade with the rest of the world. Our empirical findings indicate that CUA has not only positively impacted on Turkey's trade, but also led to changes in the behaviour of both exports and imports with regards to their responsiveness to underlying variables.     

ESTIMATING THE IMPACT OF IMMIGRANTS ON THE HOST COUNTRY SOCIAL SECURITY SYSTEM WHEN RETURN MIGRATION IS AN ENDOGENOUS CHOICE*

This article estimates immigrants’ fiscal impact on the German pension insurance and unemployment insurance systems when return migration is an endogenous choice. For this purpose, it develops a dynamic stochastic model of joint return migration and saving decisions and estimates it using longitudinal data on immigrants from five countries. The results indicate that exogenous return migration—which has been the practice of the literature so far—underestimates the state coffers’ net gain substantially; e.g., the unemployment insurance system’s net gain from Turks arriving after age 30 falls by an amount that is roughly equal to their annual earnings at arrival.     

The Pricing of Equity Carve-Outs

This article examines the pricing of stock for 251 equity carve‐outs during the 1986–1995 period. We document a mean initial‐day return of 5.83% and a mean one‐week return of 5.43%. Among carve‐outs, the initial underpricing is lower for issues represented by high prestige investment bankers and those that have a lower offer price. In comparison with 251 initial public offering (IPO) firms matched by size and book‐to‐market ratio of equity, carveouts exhibit significantly lower initial‐day returns, but their buy‐and‐hold returns for sixmonth and one‐year periods are not significantly different from IPOs. The IPO firms have a three‐year return of 28.82% which is significantly higher than the 21.07% return for the carve‐out firms.     

The Endogenous Sequential Probit model: An application to the demand for hospital utilization

This paper develops the Endogenous Sequential Probit model to analyze the effect of managed care on hospital utilization by adult married US population and finds that managed care gives disincentives to utilize hospital care relative to the standard indemnity plans.     

The <Emphasis Type="Italic">n</Emphasis>-person Kalai-Smorodinsky bargaining solution under pre-donations

This study examines the behavior of simple n-person bargaining problems under pre-donations where the Kalai-Smorodinsky (KS) solution is operant. Pre- donations are a unilateral commitment to transfer a portion of one’s utility to someone else, and are used to distort the bargaining set and thereby influence the bargaining solution. In equilibrium, these pre-donations are Pareto-improving over the undistorted solution; moreover, when the agents’ preferences are sufficiently distinct, the equilibrium solution coincides with the concessionary division rule.     

Labor market outcomes,savings accumulation,and return migration

In this paper, I examine the determinants of return migration from Germany for immigrants from four different source countries, and test the savings accumulation conjecture that is used to rationalize return migration decisions using both cross-country and time variation in purchasing power parity. The empirical results confirm the savings accumulation conjecture. Therefore, return migration can be seen as part of optimal life-cycle location choices in this context. I also examine how labor market outcomes influence return decisions. A key finding here is that unlike previous studies, which find a positive impact of unemployment on return migration, I find that the direction of the impact of unemployment changes by the spell length.     

THE PROFITABILITY OF COLONIAL INVESTMENT

This paper develops a model for studying colonial investment in which the metropolitan government restricts the amount of investment in the colony in order to maximize the net profits earned in the colony. The model explicitly includes the threat of subversive activity by the indigenous colonial population. The analysis suggests why historically some countries but not others became colonies and why many colonies that were initially profitable subsequently become unprofitable and were abandoned. The model also has implications for the amount of investment in colonies, the allocation of indigenous colonial labor between production and subversive activity, and the distribution of income between colonial firms and the indigenous population.
