The relationship between trade liberalization and inequality has received considerable attention in recent years. The major
purpose of this study is to present new results on the sources of wage inequalities in manufacturing taking into account South–South
(S–S) trade. Globalization has not only lead to increasing North–South (N–S) trade, but it has also changed the direction
and composition of trade as more trade is carried out among developing countries. In this study, we find that increasing wage
inequality is associated more with the South–South trade liberalization than with the classical trade liberalization with
northern countries. A part of this increasing wage inequality due to S–S trade comes from the development of N–S trade relationship
in S–S trade that increases wage inequality in middle-income developing countries. This study also seeks to shed some light
on the link between the direction of trade and technological change. We explore the fact that S–S trade leads to a technological
change biased toward skill-intensive sectors more than N–S trade. This indirect effect increases wage inequality for all developing
countries, but it is more important in low-income countries. 相似文献

This article brings new insights on the role played by (implied) volatility on the WTI crude oil price. An increase in the volatility subsequent to an increase in the oil price (i.e. inverse leverage effect) remains the dominant effect as it might reflect the fear of oil consumers to face rising oil prices. However, this effect is amplified by an increase in the oil price subsequent to an increase in the volatility (i.e. inverse feedback effect) with a two-day delayed effect. This lead-lag relation between the oil price and its volatility is central to any type of trading strategy based on futures and options on the OVX implied volatility index. It is of interest to traders, risk- and fund-managers. 相似文献

Mediterranean bluefin tuna have been increasingly overfished since the early 1990s, but the countries involved have so far
been unable to reach an agreement on an ecologically and economically more efficient use of this shared resource. A system
of individual transferable quotas could foster international agreement on reducing the total allowable catches. One condition
for this, however, would be that fisheries be adequately compensated for the opportunity costs of decommissioning vessels. 相似文献

Over the past 25 years, real average hourly wages in the United States have become substantially more volatile relative to output. Microdata from the Current Population Survey (CPS) is used to show that this increase in relative volatility is predominantly due to increases in the relative volatility of hourly wages across different groups of workers. Compositional changes of the workforce, by contrast, account for only a small fraction of the increase in relative wage volatility. Simulations with a Dynamic Stochastic General Equilibrium (DSGE) model illustrate that the observed increase in relative wage volatility is unlikely to come from changes outside of the labor market (e.g. smaller exogenous shocks or more aggressive monetary policy). By contrast, greater flexibility in wage setting due to deunionization and a shift towards performance-pay contracts as experienced by the U.S. labor market is capable of accounting for a substantial fraction of the observed increase in relative wage volatility. Greater wage flexibility also decreases the magnitude of business cycle fluctuations, suggesting an interesting new explanation for the Great Moderation. 相似文献

Vertical integration theory has long suggested internal costs related to changes in incentives due to vertical integration, which means that vertical integration may lead to agency costs. In this work, we specify the notion of agency costs of vertical integration and extend Ang et al. (2000)'s measurement of agency costs to provide an empirical assessment of these costs in the French wine industry. Our econometric analysis finds that the agency costs of vertical integration may reach 2–3% of sales. It also showed that operating expenses of vertical integration are lower for cooperatives than for other firms, while vertical integration is less rewarding for them. This raises questions on the relation between agency costs in cooperatives and their performance. 相似文献

This paper considers a generalization of the Stackelberg model to cover a T‐stage framework with several leaders and followers who compete on quantities. Assuming a linear demand function and constant marginal costs, we introduce constant conjectural variations in order to capture various structures of competition. First, we characterize the equilibrium market outcome. Second, we study the influence of conjectures on welfare. We notably propose a welfare comparison for six symmetric equilibria. Third, we consider convergence analysis, and we also show that the competitive equilibrium is a consistent oligopoly equilibrium. 相似文献

Technological Scanning by Small Canadian Manufacturers 总被引:4,自引:0,他引:4
Louis Raymond Pierre-André Julien & Charles Ramangalaby 《Journal of Small Business Management》2001,39(2):123-138
Given that in many industries new production and information technologies have fundamentally changed the way in which firms must operate and compete, the technological aspect of environmental scanning has become a critical success factor for many small and medium-sized manufacturing enterprises. As little is presently known about how technological scanning manifests itself in these organizations and about what determines the nature and level of this activity, a survey study of 324 Canadian firms was done. Testing a research model resulted in identifying four interrelated dimensions of scanning activity, namely scanning objectives, type of information, information sources, and management practices. Key determinants of this activity were also identified, including the firms' strategy, environmental uncertainty, production technology, level of R&D, information networks, and the owner-manager's education level. 相似文献

Most economists agree in their view of small and medium-sized enterprises, or small businesses (SMEs), as a marginal scientific subject. They may go so far as to ignore them, either because they think these economic units do not lend themselves to conventional economic studies — studies which, for instance, take into account the sacred cow theory of economies of scale — or because they see them as being not really different from big businesses.However, at least a few economists have recognized, first, the many characteristics differentiating SMEs from big firms, and second, their increasing importance in terms of numbers and job creation within economies. Among these few, Schumpeter was one of the first to show the importance of entrepreneurs and SMEs as the main variable of change in an economy. Simon and Lucas also explained the difference between small and big firms through the differing abilities required by managers to run them. Penrose looked at the question from another point of view by highlighting the interstices taken up by SMEs to fulfil needs that cannot be fulfilled by bigger units. Critics of the theory of economies of scale showed that such economies may be offset by a number of diseconomies, thus justifying the efficiency of many SMEs. More recently, Mills and Schumann suggested that SMEs compensate for their lack of economies of scale by their production flexibility, particularly in today's turbulent economy.The limits of traditional economic theory are clearly demonstrated by the fact that it does not take account of all these theories, concepts and ideas. It thus neglects a number of important economic phenomena, including the persistence and current expansion of SMEs. Consideration of such phenomena may lead to the development of a new economic theory based on the concepts of instability and contingency, together with the behaviour of entrepreneurs and small firms, thus tending to contradict, in particular, the concept of equilibrium in conventional economic theory.A first version of this paper has been presented as invited speaker at the symposium of TETRA Group at Lyon, France, 30–31 May 1990. I thank the colleagues Fritz Rieger, Frances Solé Parrellada, Jacques Filion and the two referees for their very interesting suggestions on a preliminary second version. 相似文献
