Regional integration and innovation offshoring with occupational choice and endogenous growth

We study the effects of regional integration on patterns of production and offshoring in a two-region model of occupational choice and endogenous growth. The distribution of asset wealth and allocation of heterogenous workers into innovation and production determines relative market size. When trade costs and knowledge dispersion are high (low), the asset wealthy (poor) region has a larger market and greater shares of innovation and manufacturing. For low to intermediate levels of trade costs, innovation and manufacturing offshoring flows toward the larger region, but when trade costs and knowledge dispersion are high, offshoring flows from the larger asset wealthy region to the smaller asset poor region. Economic growth is unaffected by the shifts in innovation and production that coincide with changes in relative market size.     

Constitutional choice and European immigration policy

The EU’s immigration policy is evaluated from the standpoint of constitutional economics. The main conclusion is that European immigration policy is trapped in a system of constitutional regulations that is too rigid as it is exclusively oriented towards the protection and securitisation of European borders. As such, it is not capable of allowing the development of a problem-solving capacity based on successive trials, and this produces negative outcomes for the whole of the EU.

A model of wage and employment effects of service offshoring

This paper develops a two‐sector model of trade in goods and intermediate tasks that differ in tradability and skill intensity. A skill‐abundant country with high productivity is shown to offshore more unskilled tasks than skilled tasks, without relying on a particular correlation structure between tradability and skill intensity. With putty‐clay technology that allows retraining in the long run, transition from the non‐offshoring to the offshoring equilibrium generates wage and employment effects that switch from negative to positive as tradability declines, with the switches occurring at a higher degree of tradability for skilled tasks. This is consistent with the empirical literature.     

Credit crunch in a model of financial intermediation and occupational choice

In this paper, we introduce a dynamic general equilibrium model with numerous and heterogeneous investment projects and endogenous occupational choice to study a credit crunch. Asset accumulation of assets by households as they face various employment and return risks over a long lifetime determines whether they are entrepreneurs or workers. The origin of a credit crunch may be found in the conservative lending by banks during periods of financial duress and reduced profitability because of capital requirements. Using an example from Canada, monetary policy is shown to be largely ineffective in alleviating the credit crunch, while flexible loan regulation can erase it.     

Symbolic values, occupational choice, and economic development

Channeling human resources into occupations with high social productivity has historically been a key to economic prosperity. Occupational choices are not only driven by the material rewards associated with the various occupations, but also driven by the esteem that they confer. We propose a model of endogenous growth in which occupations carry a symbolic value that makes them more or less attractive; the evolution of symbolic values is endogenously determined by purposive transmission of value systems within families. The model sheds light on the interaction between cultural and economic development and identifies circumstances under which value systems matter for long-run growth. It shows the possibility of culturally determined poverty traps and offers a framework for thinking about the transition from traditional to modern values.     

Child allowances,educational subsidies and occupational choice

This paper examines the effects on occupational choice and capital accumulation attributable to government policies of child allowances and educational subsidies. We show that multiple steady states may arise under these two policies, with club convergence occurring, and the initial condition being of relevance, if the tax rate of labor income for skilled labor is fairly high. Under a policy of child allowances, an increase in the tax rate is found to raise the quantity of children, but lower the quality of adults; however, under a policy of educational subsidies, with an increase in the tax rate, corresponding increases are found in both the quantity of children and the quality of adults. For developed countries, introducing child allowances may improve or hurt the welfare while introducing educational subsidies is welfare improving.     

Entrepreneurial talent, occupational choice, and trickle up policies

We study market inefficiencies and policy remedies when agents choose their occupations, and entrepreneurial talent is subject to private information. Untalented entrepreneurs depress the returns to entrepreneurship because of adverse selection. The severity of this problem depends on the outside option of entrepreneurs, which is working for wages. This links credit, product and labor markets. A rise in wages reduces the adverse selection problem. These multimarket interactions amplify productivity shocks and may generate multiple equilibria. If it is impossible to screen entrepreneurs then all agents unanimously support a tax on entrepreneurs that drives out the less talented ones. However, if screening is possible, e.g., if wealthy entrepreneurs can provide collateral for their loans, then wealthy entrepreneurs do not support surplus enhancing taxes.     

A model of the skill composition of US immigration

A human capital model is specified to explain the skill composition of US immigration. A unique set of panel data (57 source countries and 15 annual observations) and a methodology not previously used to study a demographic phenomenon are employed to estimate the model. Coefficients on time-invariant variables are recovered by means of the Hausman - Taylor instrumental variable procedure, which yields considerably different results than the generalized least squares model.     

Female labor-force participation,occupational choice,and fertility in developing countries

A model is presented in which female labor-force participation, family size, occupation, and the demand for mother-substitutes are joindy determined under assumptions relevant to the less developed country (LDC) context. The model is tested using (1) household data from the 1970 Puerto Rican Public Use Sample and (2) an intercountry cross-section sample. Evidence is obtained that female potential wages rising pari passu with each other will be positively associated with both labor force participation and fertility. However, it is shown that this pronatalist effect may not hold for potential wage rate rises limited to specific occupations, because of differences in occupation-child-rearing compatibility.     

Risk preference,immigration policy and illegal immigration

The paper analyzes the effects of government policy upon illegal immigration. The model used as a vehicle for this analysis is an extension of Ethier's one-small-country model of illegal immigration to a two-country context. We distinguish between the cases of capital immobility and free capital mobility, and consider illegal immigration when there are border patrols by the government and when there are internal enforcement procedures in effect. Unlike previous researchers who have assumed risk neutrality, we examine the impacts of government policy when prospective illegal immigrants exhibit risk averse and risk loving behavior. The relaxation of the risk neutrality assumption leads to the possibility of multiple and unstable equilibria. Moreover, attitudes to risk and the probability of detection are shown to have implications for some equilibrium responses to tighter surveillance.     

Managerial capital,occupational choice and inequality in a global economy

This study proposes a simple theory of trade with endogenous firm productivity, occupational choice and income inequality. Individuals with different managerial talent choose to become entrepreneurs or workers. Entrepreneurs enhance firm productivity by investing in managerial capital. The model generates three income classes: low‐income workers facing the prospect of unemployment, middle‐income entrepreneurs managing domestic firms and high‐income entrepreneurs managing global firms. Trade liberalization policies raise unemployment and improve welfare. A reduction in per‐unit trade costs raises top incomes and generates labour‐market polarization. A reduction in fixed exporting costs has an ambiguous effect on top incomes and personal income distribution. Policies reducing labour‐market frictions or the costs of managerial‐capital acquisition create more jobs and improve welfare. The income distributional effects of labour‐market policies depend on which policy is implemented.

Persistent income gaps in an occupational choice model with multi‐goods

In this study, we propose a theory to explain why income gaps persist. We model a simple overlapping‐generations economy with three consumption goods and two types of workers. We find that high‐skilled workers have comparative advantage in skill‐intensive jobs and low‐skilled workers in less skill‐intensive jobs. This pattern of comparative advantage determines occupational choices by workers. Combined with human capital accumulation, the occupational choices widen income gaps between families. At the same time, the relative price of skill‐intensive goods declines owing to productivity improvement. The decline holds back income gaps from exploding. The implications of skill‐biased technological change are also examined.     

Financial constraints and occupational choice in Thai villages

Financial constraints and entrepreneurship are key factors affecting economic performance in developing countries. I formulate and solve a model of occupational choice with moral hazard under three alternative financial market environments: savings only, borrowing and lending with default and moral hazard constrained insurance. I use computationally efficient techniques based on mechanism design, genetic algorithms and maximum likelihood to estimate and statistically test these models of financial constraints. Using occupational choice data from Thai villages I find evidence that the saving only regime is rejected in favor of regimes allowing for borrowing and/or insurance, especially in higher-wealth data stratifications. A direct test between the borrowing and insurance regimes reveals that neither can be rejected in favor of the other. Allowing ex-ante lotteries over wealth improves the explanatory power of the model. I also find evidence for differences in the best fitting regimes by region, wealth, and access to formal credit.     

Downstream offshoring and firm-level employment

When engaging in offshoring, firms import not only intermediates they used to produce in-house but also intermediates they previously sourced from non-affiliated domestic suppliers. This leads to a negative demand shock for the latter. We label this demand shock “downstream offshoring” and develop a novel measure capturing its extent for a firm in a given upstream industry. According to our instrumental variables estimations for a rich sample of Belgian manufacturing firms for the period of 1997 to 2007, downstream offshoring has a robust negative effect on employment.     

Sources of TFP growth: occupational choice and financial deepening

This paper explains and measures the sources of total factor productivity (TFP) by developing a method of growth accounting based on an integrated use of transitional growth models and micro data. We decompose TFP growth into the occupational-shift effect, financial-deepening effect, capital-heterogeneity effect, and sectoral-Solow-residuals. Applying this method to Thailand, which experienced rapid growth with enormous structural changes between 1976 and 1996, we find that 73% of TFP growth is explained by occupational shifts and financial deepening, without presuming exogenous technical progress. Expansion of credit is a major part. We also show the role of endogenous interaction between factor price dynamics and the wealth distribution for TFP.

Labor market structure and offshoring

We consider a two‐country, two‐sector model in which a firm’s offshoring decision depends on labor market rigidities that impose additional costs on the firm. Firms endogenously choose their organizational form considering their productivity level and organizational costs. The costs generated by labor market frictions play a key role in determining the benefits of each organizational structure, and thus helps determine the conditions under which a firm decides to offshore. There are three different types of equilibria depending on the relative levels of the domestic and foreign labor market costs and the price of the intermediate input. In all equilibria, a relative rise in the domestic labor market cost increases the share of firms that offshore, while decreasing domestic integration. Furthermore, an economy with offshoring has a higher welfare level and a lower unemployment rate than it would under autarky.     

Productivity and offshoring innovative activities

Recent studies suggest that firms may gain from global sourcing of innovative activities. Yet, only a small number of firms offshore their R&D, design, and engineering tasks. To explain this selection pattern, this paper examines the heterogeneity in total factor productivity among a large group of European firms. The results suggest that those firms that offshore their innovative activities tend to be more productive than domestic firms, exporters, and other multinational corporations. This finding implies that firms with superior productivity are more likely to exploit the global task distribution in innovative activities, which may provide an explanation for why such low participation is observed in the data.     

A formal model of theory choice in science

Summary. Since the work of Thomas Kuhn, the role of social factors in the scientific enterprise has been a major concern in the philosophy and history of science. In particular, conformity effects among scientists have been used to question whether science naturally progresses over time. Using neoclassical economic reasoning, this paper develops a formal model of scientific theory choice which incorporates social factors. Our results demonstrate that the influence of social factors on scientific progress is more complex than previously thought. The patterns of theory choice predicted by the model seem consistent with historical episodes of theory change. Received: April 8, 1997; revised version: April 30, 1998
