Trade with Time Zone Differences: Factor Market Implications

The main purpose of this study is to illustrate, with a simple two‐factor (skilled and unskilled labor) model, how a time‐saving improvement in business‐services trade benefitting from differences in time zones can have an impact on national factor markets. In doing so, we intend to capture the situation where the night‐shift work in one country is replaced by the day‐shift work in another country. In other words, we will show that trade with time zone differences will result in shifts of the relative supplies and demands for skilled labor around the globe.     

NETWORK EXTERNALITIES AND COMPARATIVE ADVANTAGE

In this article, I examine how the network externalities of communications activities and trading opportunities interact to determine the structure of comparative advantage. These interactions are examined by constructing a two‐country, three‐sector model of trade involving a country‐specific communications network sector. The role of the connectivity of network providers, which allows users of a network to communicate with users of another network, is also explored.     

On the performance of tests by Wu and by Hausman for detecting the ordinary least squares bias problem

We first consider the performance of the Wu (1973) - Hausman (1978) (W-H) specification error test as a test for the existence of ordinary least squares (OLS) bias. We discuss power properties of the test under alternative null hypotheses, one of which has not previously been considered. We next consider how the W-H test performs as an indicator of the extent (rather than the existence) of an OLS bias problem, since this usage of the test seems common in applied studies. Finally Monte Carlo methods are used to evaluate Wu's two-step estimation procedure involving the W-H test as a pretest.     

Interconnectivity of communications networks and international trade

Abstract In this study a multi‐country model of trade is developed that captures the role of country‐specific communications network interconnectivity, which enhances trade in intermediate business services. The number of countries connected to internationally interconnected networks is found to determine the structure of comparative advantage. That is, countries with interconnected networks have a comparative advantage in the good that requires business services provided via networks. In connected countries, producers of that good benefit from the efficient transmission of business services. This research also demonstrates that countries whose country‐specific networks are not connected to the interconnected networks may become worse off as the result of trade.

Interconnectivité des réseaux de communication et commerce international Ce mémoire développe un modèle de commerce international impliquant plusieurs pays qui cerne le rôle de l'interconnectivité des réseaux de communication de chaque pays. Cette interconnectivité enrichit les flux de commerce dans les services intermédiaires d'affaires. Il appert que le nombre de pays connectés aux réseaux internationalement connectés détermine la structure de l'avantage comparatif. Ce qui veut dire que les pays qui ont des réseaux interconnectés ont un avantage comparatif dans le bien qui requiert les services d'affaires fournis par les réseaux. Dans les pays connectés, les producteurs de ces biens bénéficient de la transmission efficace de ces services d'affaires. La recherche montre aussi que les pays dont les réseaux nationaux ne sont pas connectés aux réseaux interconnectés peuvent voir leur situation s'empirer en conséquence du commerce international.     

Dynamic Seemingly Unrelated Cointegrating Regressions

We propose the parametric Dynamic Seemingly Unrelated Regression (DSUR) estimator for simultaneous estimation of multiple cointegrating regressions. DSUR is efficient when the equilibrium errors are correlated across equations and is applicable for panel cointegration estimation in environments where the cross section is small relative to the available time series. We study the asymptotic and small sample properties of the DSUR estimator for both heterogeneous and homogeneous cointegrating vectors. We then apply the method to analyse two long-standing problems in international economics. Our first application revisits the estimation of long-run correlations between national investment and national saving. Our second application revisits the question of whether the forward exchange rate is an unbiased predictor of the future spot rate.     

Business Groups and the Big Push: Meiji Japan's Mass Privatization and Subsequent Growth

Paul Rosenstein-Rodan argues that economic development requirescoordinated investment in many interdependent industries, andprescribes a flood of state-controlled investment across allsectors—a so-called big push. Widespread government failuredefeated twentieth-century ‘big push’ schemes. Butspillovers across firms and industries, and from public goods,hold-up problems, and capital market limitations are real, andjustify coordinated growth across sectors if it can be donewithout government failures. Large, extensively diversifiedpyramidal business groups of listed firms dominate the historiesof developed economies and the economies of developing economies.Arguing that such groups provided this coordination in prewarJapan after a state-run big push failed, we propose that pyramidalbusiness groups are private-sector mechanisms for coordinatingbig push growth, and that competition between rival groups inducesefficiency unattainable in a state-run big push. We postulatethat a successful business-group led big push requires economicopenness, basic public goods, rule of law, separation of thestate from business, and a timely demise of business groupswhen the big push phase is complete. Where these criteria arenot met, growth stalls and oligarchic families become too powerfulto dislodge.     

Virtual integration and endogenous growth in the world economy

This study develops a three-country model of endogenous growth that captures the role of the interconnection of country-specific communications networks (i.e., virtual integration), which affects the productivity of R&D activity through an increase in stock of knowledge capital. The number of countries connected to internationally interconnected networks is found to determine the structure of dynamic comparative advantages. That is, countries with interconnected networks have a dynamic comparative advantage in differentiated products that require communication and activities. In the connected countries, researchers gain from efficient activity through the utilization of the greater stock of knowledge capital.

A New Dynamic Trade Model of Increasing Returns and Monopolistic Competition

This paper formulates a two‐country by two‐factor by two‐good dynamic Chamberlin–Heckscher–Ohlin model of international trade with endogenous time preferences. After proving the existence, uniqueness and local saddle‐point stability of the steady state, we examine the relationship between initial factor endowment and trade patterns in the steady state. It will be shown that (i) given that the representative household in each country supplies an equal amount of labor, only intra‐industry trade occurs in the steady state and (ii) other things being equal, the country with higher labor efficiency becomes the net exporter of the labor‐intensive good.
