This paper analyses the contribution of fundamental comparative advantage (a country-specific component) and granular comparative advantage (a firm-specific component) to European Union countries' export specialisation. We find that, on average, granular comparative advantage may explain export specialisation in 29% of industries, which account for 47% of total exports. We also show that 60% of the variation in export specialisation across countries and industries may be explained by granular comparative advantage. These results highlight that some outstanding firms may play a very important role in explaining European Union countries' export specialisation. 相似文献

This study investigates under which circumstances trade has impact on inflation dynamics by examining the independent effects of trade intensity, intra-industry trade and trade on value added. Trade in goods is decomposed into consumption (final) goods and intermediate inputs to deepen the assessment of the role of the globalisation of production activities on inflation dynamics. Open-economy new Keynesian Phillips curve (NKPC) analyses suggest that inflation is sensitive to domestic factors and that the relevance of external factors changes with respect to the nature of trade, country groups and time. Vertical intra-industry trade in intermediate inputs and value-added trade play important role, whereas final goods trade has no statistically significant effect on inflation dynamics. 相似文献

This paper considers the extent to which South African households have deleveraged, since the global financial crisis of 2007/2008. We extend the official South African Reserve Bank business cycle methodology to date financial cycles, from which we identify the peaks and troughs of the South African financial cycle going back to 1966. Our composite financial cycle index peaks in April 1974, January 1984 and May 2007; it has bottomed out in July 1979 and February 1999. Thus, we still await the trough. We further compare and contrast the deleveraging process in the current downward phase to the experiences from previous financial cycles. We find that the average period of the financial cycle in South Africa is much longer (approximately 17.3 years) than that of the business cycle (approximately 5.8 years), and that deleveraging has not yet matched the degree of deleveraging seen in previous downward phases. Our results suggest that further deleveraging is necessary, before we can expect to turn the financial corner. 相似文献

Excess market returns are correlated with past market variance. This dependence is statistically mild at short horizons (thereby leading to a hard-to-detect risk-return trade-off, as in the existing literature) but increases with the horizon and is strong in the long run (i.e., between 6 and 10 years). From an econometric standpoint, we find that the long-run predictive power of past market variance is robust to the statistical properties of long-horizon stock-return predictive regressions. From an economic standpoint, we show that, when conditioning on past market variance, conditional versions of the traditional CAPM and consumption-CAPM yield considerably smaller cross-sectional pricing errors than their unconditional counterparts. 相似文献

Searching for efficient networks can prove a very difficult analytical and even computational task. In this paper, we explore
the possibility of using the genetic algorithms (GA) technique to identify efficient network structures in the case of non-trivial
payoff functions. The robustness of this method in predicting optimal networks is tested on the two simple stylized models
introduced by Jackson and Wolinsky (1996), for which the efficient networks are known over the whole state space of the parameters’
values. This approach allows us to obtain new exploratory results in the case of the linear-spatialized connections model
proposed by Johnson and Gilles (Rev Econ Des 5:273–299, 2000), for which the efficient allocation of bilateral connections
is driven by contradictory forces that push either for a centralized structure around a coordinating agent, or for only locally
and evenly distributed connections.

We study the impact of tax and transfer programs on steady-state allocations in a model with search frictions, an operative labor supply margin, and incomplete markets. In a benchmark model that has indivisible labor and incomplete markets but no trading frictions we show that the aggregate effects of taxes are identical to those in the economy with employment lotteries, though individual employment and asset dynamics can be different. The effect of frictions on the response of aggregate hours to a permanent tax change is highly nonlinear. There is considerable scope for substitution between “voluntary” and “frictional” nonemployment in some situations. 相似文献

The authors explore the effect of medium of instruction on students' attainments at a large state university in Turkey in the Department of Business Administration. The findings indicate no statistically significant difference in grades of 386 students with respect to medium of instruction. As for entry rankings however, those in the English-medium program who had higher scores on the university entrance exam appeared to be more successful. It may be concluded that English-medium instruction is not a disadvantage in attaining learning objectives. 相似文献

Empirical evidence suggests that exporter firms tend to charge higher markups than non-exporters due to trade barriers. The exporters’ markup premium, however, may disappear in a special case, namely when the home country is small relative to its trade partners and trade barriers are low. This can be because competition is more intense in the large export destination than in the small home country, so that firms are able to set higher markups for locally sold products but not for exports. This paper provides empirical evidence on the validity of this special case by estimating markups for firms in Luxembourg who generally export to larger countries. The estimated negative markup premium for exporters has important implications for the productivity measurement. In a sufficiently small open economy, exporters’ productivity may be biased downward, when the firm-level markup variation is not controlled for in the productivity estimation. The bias in the productivity estimates further leads to the inaccurate conclusion that openness to international trade lowers allocative efficiency. 相似文献

This paper provides a framework with which to analyze organizational forms in the knowledge economy. We focus on an important trade-off facing modern firms: firms can acquire the property of all the innovations developed by their employees and can greatly increase their profits, yet this type of private intellectual property rights regime can discourage the innovative effort of the very same workers. Allowing workers to carry their knowledge outside the firm eliminates this disincentive. Hence, strategic complementarities may exist between innovative partners and a disclosure driven intellectual property rights regime, and passive employees and a private intellectual property rights regime. An evolutionary game theoretic model demonstrates these strategic complementarities and shows when economies tend towards disclosure driven or private intellectual property rights regimes. 相似文献
