A nested model is presented which has both the sequential and the multinomial logit model as special cases. This model provides a simple test to investigate the validity of these specifications. Some theoretical properties of the model are discussed. During the analysis a distribution function is derived, which, to the best of our knowledge, has not been used before. This distribution is shown to be a generalization of the typeI extreme-value distribution. Monte Carlo experiments and empirical applications of the model are presented. 相似文献

The way of accounting for vertical integration, of this paper is based on the ‘Porterian’ value system and focuses on the relation between the creation and appropriation of value. The essence of a value system is that at each stage in the system value is created and added to the value created at previous stages. We propose that firms which are unable to appropriate the value they create at the stage they currently inhabit, would find it advantageous to integrate vertically towards stages offering a more attractive relation between value appropriation and value creation. This argument will be illustrated here by the case of a large Dutch bank that integrated vertically towards securities trading. 相似文献

This paper re-designs the New Keynesian model developed by Ireland (2004) and then uses the Vietnamese data from January 1995 to December 2012 to estimate the model's parameters. The empirical results show that the State Bank of Vietnam had been more aggressive as well as more responsive to aggregate fluctuations in the period before August 2000 than in the latter period. Thus, this change in the policy stance could be a potential reason for the declining importance of monetary policy in generating movements in output growth, inflation, interest rate, and the output gap across the subsamples. Another notable finding is the dominant role of the cost-push shock in explaining fluctuations in inflation, interest rate, and the output gap, leading to a policy implication that more attention should be devoted to developing substitute and complement industries so as to mitigate negative effects of the cost-push shocks by reducing the degree of dependence on imports. 相似文献

This paper examines the linkage between patenting and export performance for selected countries at the level of technology fields. Some empirical studies show considerable correlation between the patenting behavior of countries and their economic success in international markets. Adding to the existing literature, the aim of this analysis is to assess whether the indicators that are supposed to reflect patent value—such as patent citations or family size—have any explanatory power in estimating the export value of countries by technology fields. 相似文献

Forecasting the evolution of security co-movements is critical for asset pricing and portfolio allocation. Hence, we investigate patterns and trends in correlations over time using weekly returns for developed markets (DMs) and emerging markets (EMs) over the period 1973–2012. We show that it is possible to model co-movements for many countries simultaneously using BEKK, DCC, and DECO models. Empirically, we find that correlations have trended upward significantly for both DMs and EMs. Based on a time-varying measure of diversification benefits, we find that it is not possible to circumvent the increasing correlations in a long-only portfolio by adjusting the portfolio weights over time. However, we do find some evidence that adding EMs to a DM-only portfolio increases diversification benefits. 相似文献

Global warming is currently an important item on most nationalenvironmental agendas. In many countries, coal-fired electricity generatingstations represent an important source of greenhouse gases. We examinehow regulations to curb emissions affect public utility pricing regulationwhen regulators act non-cooperatively. We show that, when there is limitedinformation on fixed abatement costs, an environmental regulator prefersan emission tax over an output tax or a lump sum environmental tax. Thepublic utility regulator prefers the lump sum tax regime. 相似文献
