We model strategic interaction in a differentiated input market as a game among two suppliers and n retailers. Each one of the upstream firms chooses the specification of the input which it will offer.Then, retailers choose their type from a continuum of possibilities. The decisions made in these two first stages affect the degree of compatibility between each retailer's ideal input specification and that of the inputs offered by the two upstream firms. In a third stage, upstream firms compete setting input prices. Equilibrium may be of the two-vendor policy or of the technological monopoly type. 相似文献

Abstract We consider the pricing problem of equity-linked annuities and variable annuities under a regimeswitching model when the dynamic of the market value of a reference asset is driven by a generalized geometric Brownian motion model with regime switching. In particular, we assume that regime switching over time according to a continuous-time Markov chain with a finite number state space representing economy states. We use the Esscher transform to determine an equivalent martingale measure for fair valuation in the incomplete market setting. The paper is complemented with some numerical examples to highlight the implications of our model on pricing these guarantees. 相似文献

This paper analyzes a firm's dynamic decisions: i) whether to issue a callable or non-callable bond; ii) when to call the callable bond; and iii) whether to refund it when it is called. We argue that a firm uses a callable bond to reduce the risk-shifting problem in case its investment opportunities become poor. Our empirical findings support this argument. We find that a firm facing poorer future investment opportunities is more likely to issue a callable bond than a firm facing better investment opportunities. In addition, a firm with a higher leverage ratio and higher investment risk is more likely to issue a callable bond. Finally, after a callable bond is issued, a firm with a poor performance and a low investment activity tends to call back a bond without refunding; a firm with the best performance and highest investment activity tends to call back a bond and refund its call; and a firm with mediocre performance and investment activity tends to not call its bonds. 相似文献

Greek public pension funds can invest up to 23% into risky assets and are not allowed to invest outside Greece. This paper seeks to investigate the costs of investment constraints on pension fund portfolios. In particular we try to quantify the losses that portfolios suffer due to under-diversification and sub-optimal asset allocation. We find that the high concentration of Greek equity portfolios imposes a substantial return and utility loss which is further increased when the lack of international diversification is taken into account. Restricting the weight of equities to 23% of the total portfolio, leads to sub-optimal asset allocation that costs as much as 2% (3%) per annum compared to a balanced domestic (global) benchmark. 相似文献

This paper examines the price spread between voting (common) and non‐voting (preferred) stocks during the period 1990–95 for a sample of 55 Greek companies. Because in Greece preferred stocks are not essentially different from common stocks, a number of hypotheses were tested to explain the observed differences. The data reveal an average spread of 27.5% for the entire period which, however, varies across years considerably. In cross‐sectional regressions it was found that the volatility of common stock returns, the liquidity of common shares relative to preferred shares, the ownership concentration, and the minimum dividend yield guaranteed to preferred stockholders explain a significant portion of the spread. 相似文献

A number of theoretical studies have predicted that preferential trade agreements (PTAs) raise outside multinationals’ incentive to invest in the participating countries, especially in those that are integrated with larger markets and have lower production costs. The hypothesis has, however, not been tested empirically. This paper addresses the issue by estimating the impact of PTAs on countries’ ability to attract multinationals. The evidence is broadly consistent with expectations. The formation of PTAs leads to an increase in FDI by outside multinationals, but the effect varies sharply with the size of integrated markets and countries’ comparative advantage. Countries integrated with larger markets experience a greater increase in total and export-platform FDI. Those with a higher labor endowment also attract more FDI especially in labor-intensive industries, but at the expense of their labor-scarce PTA partners. 相似文献

On Licensing Under Bertrand Competition 总被引:10,自引:0,他引:10
This paper considers licensing by an innovating firm to its competitor in a differentiated duopoly with Bertrand competition. A principal finding is that royalty licensing may be superior to fee licensing for the innovating firm both when the innovation is drastic and when the innovation is non-drastic. 相似文献

This article analyses the stochastic income convergence within the EU-15. The empirical analysis uses per capita GDP, in PPP and in constant prices of 2005 for the period 1950 to 2010. Apart from the traditional DF type tests we also account for possible structural changes. In this direction, we employ the Zivot-Andrews (1992) and the Lee-Strazicich (1999, 2003) testing procedures, for one and two breaks, endogenously determined. Furthermore, we apply the Carlino and Mills (1993) methodology proposed for the detection of β-convergence. The overall evidence supports the existence of two discrete clubs, the first by the ‘cohesion countries’ (Portugal, Ireland, Greece and Spain) and the second by the remaining members. In particular, there is a clear evidence of convergence within each club, whereas between clubs there is a luck of catching-up effects. Furthermore, investigation of correlation between relative per capita GDP of each country and several factors that are often identified as growth stimulants, namely Total Factor Productivity, FDI, investment and openness confirm, with the exception of Greece, a strong association between these factors and the convergence process. However, progress in the convergence has not been uniform across countries and over time, reflecting the specific interactions between domestic and international factors and their impact on the convergence process of individual countries. 相似文献
