In this paper we consider the potential gain of a government pursuing a two-part trade policy: an import license for entry, along with a per-unit tariff on imports. The model is a two-stage game of complete but imperfect information. In the first stage, the domestic government sets trade policy, while in the second stage the home and foreign producers behave as Cournot competitors. The paper demonstrates that the optimal trade policy depends upon the number of firms, the degree of heterogeneity in cost functions, and the degree of convexity in cost functions. 相似文献

This paper empirically examines the relationship between government foreign debt and the growth rate of per capita GDP based on a total sample of 77 countries, as well as sub‐samples of various regions. Cross‐sectional estimates of the coefficient of foreign debt based on the total sample have a negative sign, but are not always statistically significant. Available data from African countries indicate that foreign debt and the growth rate of per capita GDP were negatively related at a high level of significance. For industrialized and Latin American sub‐samples, this relationship is negative but statistically insignificant. The sub‐sample Asian and other developing countries show a positive but insignificant relationship. JEL classification: F34, H6, O23. 相似文献

Announcements of syndication loans increase borrowers' shareholder wealth if they are revolving credit agreements but not if they are term loans. Share price responses to revolving credit announcements are positive and significant, whereas the wealth effect for term loans is negative and significant. The results show that announcements from both the financial press and commercial information providers can affect borrower share price reaction. Overall, single syndication announcements appear to be more newsworthy than multiple announcements reported in the financial press, and we find evidence of information leakage, post‐announcement drift, or both. 相似文献

The strategic marketing decision regarding the selection of a brand name has long been an area neglected by academic researchers. This study attempts to apply psychological theory to this important strategic decision area. Specifically, the applicability of a dual-coding theory of memory to brand name recall/recognition is tested in an experimental setting. Results indicate, on average, a significant one hour and two day recall/recognition advantage of high imagery over low imagery brand names across a variety of product categories. 相似文献

Initial margin requirements represent: (1) a cost impediment to the wealth constrained investor and (2) a potential way of mitigating excessive volatility. However, prior empirical research finds that margins are not an effective tool in reducing volatility. We consider the possibility that margins primarily affect certain stocks and investors. Specifically, we test whether margins affect individuals who, as a group, we believe to be the investors most affected when margin requirements change. Our initial empirical tests, however, do not support this contention. 相似文献

Summary. We prove existence of a competitive equilibrium in a version of a Ramsey (one sector) model in which agents are heterogeneous
and gross investment is constrained to be non negative. We do so by converting the infinite-dimensional fixed point problem
stated in terms of prices and commodities into a finite-dimensional Negishi problem involving individual weights in a social
value function. This method allows us to obtain detailed results concerning the properties of competitive equilibria. Because
of the simplicity of the techniques utilized our approach is amenable to be adapted by practitioners in analogous problems
often studied in macroeconomics.

A necessary criterion for a performance measure in corporate governance is the degree to which it mirrors how well the management
succeeds in maximizing firm value. Such a performance measure is marginal q which links changes in firm value to the investments undertaken by the management. Empirical studies of investment and performance
based on marginal q have demonstrated the usefulness of this measure. Most research however, has mainly focused on long-term performance. This
paper takes a short-term perspective and, based on the marginal q-theory, considers how firms’ market values change in the extreme stock price cycle of a stock market bubble. Using a data
set of listed Swedish corporations we find an anomaly in form of a new industry specific effect that, in addition to investment, explains changes in firm value.

We present a probabilistic model based on the one developed by Hernández Mendo and Anguera (Revista de Psicologíca Social,
16(1), 71–93, 2001). Here we have tried to break down the interaction contexts that the opposing teams are able to generate
and transform during the game. We are aware that a given player or team does not produce consistent behaviour in similar situations.
However, a degree of uncertainty is assumed to exist regarding whether the results obtained are a specific function of the
analysis used. In order to carry out this research a category system which optimized that used in the previous model was developed.
This system should enable the interaction between teams to be observed within the actual play of a soccer game. A lag sequential
analysis was performed on the basis of a coding of the behavioural flow. After describing the behavioural patterns obtained
a probabilistic model of the development of play in soccer is proposed. 相似文献

For Poisson inverse Gaussian regression models, it is very complicated to obtain the influence measures based on the traditional
method, because the associated likelihood function involves intractable expressions, such as the modified Bessel function.
In this paper, the EM algorithm is employed as a basis to derive diagnostic measures for the models by treating them as a mixed Poisson regression
with the weights from the inverse Gaussian distributions. Several diagnostic measures are obtained in both case-deletion model
and local influence analysis, based on the conditional expectation of the complete-data log-likelihood function in the EM algorithm. Two numerical examples are given to illustrate the results. 相似文献
