In this paper we present a model to evaluate transient industry effects, that is, the impact of business cycles on the industry. While the importance of the economic cycle for industry and firm performance is widely recognized, we do not know much about how much the business cycle influences industry activity. The aim of this paper is to present a method that helps to understand the relationship between the business cycle and an industry's level of activity. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

We compare a number of models of post War US output growth in terms of the degree and pattern of non-linearity they impart
to the conditional mean, where we condition on either the previous period's growth rate, or the previous two periods' growth
rates. The conditional means are estimated non-parametrically using a nearest-neighbour technique on data simulated from the
models. In this way, we condense the complex, dynamic, responses that may be present in to graphical displays of the implied
conditional mean.

We study the local turnpike property for two classes of infinite-horizon discrete-time deterministic maximization problems
which have common applications, e.g., optimal growth theory. We follow a functional-analytic approach and rely on an implicit
function theorem for the space of the sequences which converge to zero. We shall assume the existence of an optimal path which
is not necessarily a steady-state. Relying on material developped in Blot and Crettez (Decis Econo Finance 27:1–34, 2004),
“On the smoothness of optimal paths” Decis Econ Finance, 21:1–34, 2004), we provide conditions under which a variation in
the initial conditions (i.e., capital stock and discount rate) yields an optimal solution which converges toward a reference
solution when time becomes infinite. We also provide new results on bounded solutions of difference equations.
We gratefully thank the editor, Silvano Holzer, and two anonymous referees for remarks and advices on a previous version of
this paper. 相似文献

We investigate the association between board size and firm valuation for a sample of 169 firms from 2002 to 2011 in South Africa (SA). The SA corporate context is interestingly and uniquely characterised by an urgency to meet affirmative action regulations, such as black empowerment in board appointments, limited qualified and experienced directors, especially black directors, concentrated ownership, weak enforcement of corporate regulations and greater government ownership. These features make SA corporate boards perform a weaker agency (advisory, monitoring and disciplining) role than Western European and US boards, but a stronger resource dependence role, by providing access to resources, such as business contacts and contracts. This suggests that any positive impact of board size on firm valuation is likely to depend on the effective execution of the resource dependence role more than the agency role. Our results suggest that board size has a positive association with firm valuation, consistent with larger boards providing better access to resources. Overall, our results support the resource dependence role of boards more than their agency role. The results are robust across a raft of econometric models that control for different types of endogeneity, as well as different types of accounting and market-based firm valuation measures. 相似文献

We introduce asymmetric information about consumers’ transportation costs (i.e., the degree of product differentiation) in the model of Hotelling. When transportation costs are high, both firms have lower profits with asymmetric information than with perfect information. Contrarily, if transportation costs are low, both firms may prefer the asymmetric information scenario (the informed firm always prefers the informational advantage, while the uninformed firm may or may not prefer to remain uninformed). Information exchange is ex‐ante advantageous for both firms, but ex‐post damaging if transportation costs turn out to be low. If the information is unverifiable, the informed firm does not represent a reliable source of information, since it always prefers to announce that transportation costs are high and there is no contract that induces truthful revelation. 相似文献

Are Flexible Exchange Rate Regimes more Volatile? Panel GARCH Evidence for the G7 and Latin America 下载免费PDF全文
This paper investigates empirically the relationship between exchange rate (ER) regimes and volatility of real exchange rate depreciation (RERD), comparing the G7 and 17 Latin American (LA17) countries, during 1970–2010. We estimate a panel autoregressive model with generalized autoregressive conditional heteroskedasticity (GARCH) errors and regime‐specific effects on both the conditional mean and conditional variance. For the G7, we find that, relative to the fixed ER regime, only the freely floating regime shows higher RERD volatility; under the managed floating regime the RERD is equally volatile and under the crawling peg it is actually less volatile. Instead, in the case of the LA17, more flexible ER regimes are associated with more volatile RERD rates, with higher volatility under the managed floating regime than under the crawling peg and with extremely high volatility under the “freely falling” ER regime. 相似文献

The European Union Emissions Trading System (EU ETS) is in dire straits. Prone to design problems and suffering from the effects of the economic crises the scheme is criticised for its poor achievements. In this paper we will analyse some of the features of this situation from an ethical perspective. The major part is dedicated to the complications within each phase of the EU ETS and to the recent developments it has undergone. We will briefly discuss the remedies suggested by prominent commentators. Furthermore, any policy tool to tackle climate change should be evaluated in view of the profound equity issues that are inherent to the climate problem. We will evaluate the EU ETS according to two justice-based criteria, related to effectiveness and the distribution of the duties involved in climate change, respectively. We will conclude that the EU ETS, in its current form, clearly lacks fairness on both criteria. However, the biggest problem is the unwillingness of EU leaders to mend, what could be, a commendable climate policy tool. To that extent, we argue, those leaders are acting unjustly. 相似文献

Malmquist indices of productivity change in Portuguese banking: The deregulation period 总被引:1,自引:0,他引:1
This paper will evaluate productivity change in Portuguese banking using the Malmquist productivity index. The results show that between 1990 and 1997, banks in Portugal witnessed increased productivity and strong technological progress. Both small and large banks experienced higher productivity and technological change scores, while mid-sized institutions are putting more effort into catching-up policies. Rural banks have experienced strong productivity growth and are catching up with the best practices but lower levels of technological change. Urban banks show higher productivity growth and technological change levels. Government-owned banks have experienced lower levels of productivity change. Finally, the asset per employee ratio shows a positive correlation with the productivity scores, suggesting that this simple index is a good proxy for productivity. 相似文献

Industrial data are used to derive estimates of the pattern of change in wage inequality in Mexico and Brazil. Using the group decomposition of Theil's T -statistic, the paper presents monthly changes in the dispersion of industrial wages for Brazil (1976 through 1995) and for Mexico (1968 through 1998). Both countries show increases in wage dispersion over time, and a strong negative correlation is found with the rate of real economic growth. Other things equal, the later Brazilian heterodox stabilization plans seem to have reduced inequality in the short run. 相似文献
