American Regionalism and Global Free Trade

A free trade agreement supports global free trade since trade barriers tend to divert trade in favor of members, but not reduce imports. The term: 'mutual assured deterrence' is used to refer to a regional free trade association that has the feature that no member can gain individually from the imposition of a barrier against a non- member. Mutual assured deterrence is shown to be possible for a surprisingly rich set of partners. A customs union is compatible with global free trade if the vast majority of trade takes place naturally within the confines of the association. A customs union that is likely to have this property would combine countries to form a nearly exact economic replica of the globe. The economic combination of Mexico and the United States doesn't form a replica of the global economy because, compared with Asia, North America has relatively high capital per worker even after adding the Mexican workforce. However, NAFTA does seem to have the property of mutual assured deterrence, and may for that reason amount to a commitment to global free trade as well as regional free trade.

International Trade Theory: The Evidence

This paper provides a critical look at recent empirical work in international trade theory. The paper addresses the issue of why empirical work in international trade has perhaps not been as influential as it could have been. The paper also provides several suggestions on directions for future empirical research in international trade.

A Heckscher-Ohlin View of Sweden Competing in the Global Market

In this paper we explore the hypothesis that the Swedish malaise comes from the interaction of the Swedish welfare state with changes in the global marketplace. External commerce can expose Swedish workers in exporting and import-competing industries to competition from low-wage foreign workers that is incompatible with an extensive welfare system. The Heckscher-Ohlin theory that is the foundation of this paper allows a high-wage equilibrium without government intervention even though there is increasing competition from low-wage suppliers, if capital is abundant and if production is concentrated on the most capital intensive products. Then the unskilled workers can be employed at high wages either in the tradables or nontradables sector. However, Swedish investment rates have not been high enough to maintain the position that it had two decades ago. This we express in the form of the Heckscher-Ohlin Crowding Hypothesis: Swedish difficulties in its interactions with the global marketplace come from an eroding lead in capital abundance. Though losing its distinctiveness in capital abundance, Sweden remains well supplied with soft-wood forests. Although contributing substantially to GDP forest resources can also imply lower wages for unskilled workers and greater income inequality. A country with abundant forest resources and produce capital intensive products as well as pulp and paper, but a country with more moderate supplies of capital can find much of its capital deployed in pulp and paper and end up with a mix of tradables including relatively labor-intensive products. This product mix may dictate relatively low wages for unskilled workers since the marginal unskilled worker may be employed in sectors which globally award low wages.

Empirical Tests of Alternative Models of International Growth

Recent changes in patterns of international trade and growth have rekindled interest in the relationships among trade, growth, and the international distribution of income. Three alternative models can serve as a theoretical foundation for an empirical analysis of these relationships. The first is the standard Heckscher-Ohlin-Samuelson (Ho) trade model with equalnumbers of factors and goods and incomplete specialization. The second model allows complete specialization and more goods than factors. The third model posits short run capital immobility. Each of these models has quite different implications for the determination of wage levels and growth rates.The conclusions that we draw from this research are rather mixed. Each of the models perform well on certain criteria and poorly on others. While the standard HO model clearly fails to satisfy certain cross-equation constraints, national endowments are remarkably good predictors of the locus of international production. There are, however, significant nonlinearities in the relationship between factor allocations and national endowments. Such nonlinearities are predicted by the uneven version of the HO model. At odds with both of these models is our finding that lagged values of inputs providean important explanation of current factor demands. Such correlations are suggested by the adjustment cost model.

A Nonlinear Model of the Business Cycle

The usual index of leading indicators has constant weights on its components and is therefore implicitly premised on the assumption that the dynamical properties of the economy remain the same over time and across phases of the business cycle. We explore the possibility that the business cycle has phases, for example, recessions, recoveries and normal growth, each with its unique dynamics. Based on this possibility we develop a nonlinear model of the business cycle that combines a number of previous approaches. We model the state of the economy as a latent variable with a threshold autoregression structure. In addition to dependence on its own lags the latent variable is also determined by observed economic and financial variables. In turn these variables are modeled as following a nonlinear vector autoregression with regimes defined by the latent business cycle variable. A Markov Chain Monte Carlo algorithm is developed to estimate the model. Special attention is paid to specification of prior distributions given the large dimension of the model. We also investigate using the business cycle chronology of the NBER to aid in the classification of the latent variable. The two main empirical objectives of the model are to provide more accurate predictions of economic variables particularly at turning points and to describe how the dynamics differ across business cycle phasesnonlinear, business cycle, Bayesian
