Downstream Competition, Foreclosure, and Vertical Integration 总被引:2,自引:0,他引:2
Gilles Chemla 《Journal of Economics & Management Strategy》2003,12(2):261-289
This paper analyzes the effect of competition among downstream firms on an upstream firm's payoff and on its incentive to integrate vertically when firms in both segments negotiate optimal contracts. We argue that as downstream competition becomes more intense, the upstream firm obtains a larger share of a smaller downstream industry profit. The upstream firm may encourage downstream competition (even excessively) in response to high downstream bargaining power. The option of vertical integration may be a barrier to entry downstream and may trigger strategic horizontal spinoffs or mergers. We extend the analysis to upstream competition. 相似文献

Abstract
The problem of numerically pricing credit default index swaptions on a large number of names is considered. We place ourselves
in a stochastic intensity framework, where Ornstein-Uhlenbeck-type correlated processes are used to model both firms’ distance
to default and a macroeconomic state variable. Here the default of the firms’ follows the reduced-form approach and the (random)
intensity of the default depends on the behavior of the diffusion processes. We propose here a numerical method based on both
a Monte Carlo and a deterministic approach for solving PDEs by finite differences. Numerical tests demonstrate the efficiency
and the robustness of the proposed procedure. 相似文献

Communication externalities in cities 总被引:2,自引:0,他引:2
To identify communication externalities in French cities, we exploit a unique survey recording workplace communication of individual workers. Our hypothesis is that in larger and/or more educated cities, workers should communicate more. In turn, more communication should have a positive effect on wages. By estimating both an earnings and a communication equation, we find evidence of communication externalities. In larger and more educated cities, workers communicate more and in turn this has a positive effect on their wages. Depending on the estimates, we find that 13 to 22% of the effects of a more educated and larger city on wages percolate through this channel. 相似文献

This paper studies the effect of economic integrationof two regions on the mobility of skilled and unskilled workersacross regions and on the resulting location of industrial activity.In particular, we study what happens when wages in both regionsare set by the unions of the West—the region with agreater initial relative stock of human capital. We show thatunder some circumstances, it is the interest of the West's unionsto set up a speed of wage convergence greater than equilibrium,thus generating unemployment in the East. This slows the migrationof human capital toward the East, but quickens the migrationof raw labor toward the West. A greater share of economic activityis eventually located in the Western region. Unions in the Westwill benefit from this provided human capital has low migrationcosts relative to raw labor. 相似文献

Evidence suggests that in developing countries, agents rely on mutual insurance agreements to deal with income or expenditure shocks. This paper analyzes which risk-sharing networks can be sustained in the long run when individuals are farsighted, in the sense that they are able to forecast how other agents would react to their choice of insurance partners. In particular, we study whether the farsightedness of the agents leads to a reduction of the tension between stability and efficiency that arises when individuals are myopic. We find that for extreme values of the cost of establishing a mutual insurance agreement, myopic and farsighted agents form the same risk-sharing networks. For small costs, farsighted agents form efficient networks while myopic agents don’t. 相似文献

This paper addresses the issue of how sustainable supply practices are actually used as a leverage for sustainable development (SD). In order to assess the level of sustainable supply management within an organization, the authors have reviewed the literature extensively and then developed a five‐step maturity model around five management dimensions. A qualitative exploratory approach based on two detailed case studies of organizations whose reputation for SD is recognized internationally has been used. This methodology allowed us to show (1) how sustainable supply practices could be used as a leverage for an organization's sustainable development approach and (2) that sustainable supply practices still have quite a distance to go with regards to the maturity model for sustainable supply, even in organizations that are often mentioned as leaders in the SD area. In these organizations, managers still emphasize environmental considerations, while neglecting practices that would make it possible to reach the three SD objectives simultaneously.

The paper examines the monetary policy actions through which central banks in sub‐Saharan Africa have tried to eliminate the negative impacts of the shocks facing their economies. We compare two different monetary policy regimes: a currency board regime (in the CFA zone) and an inflation targeting policy regime (Ghana and South Africa) when central banks respond to demand, supply, and fiscal shocks. We extend the usual forecasting and policy analysis system models to replicate the economic features of these economies during the period 2002–12 and to evaluate the impact of several policies in response to these shocks. We find that both policies are inappropriate in helping the economies escape from the effects of negative demand shocks, both are essential when negative shocks to primary balance occur, while inflation targeting dominates the currency board regime as a strategy to cope with positive shocks to inflation. 相似文献

This paper studies the dynamics of fundamental research. We develop a simple model where researchers allocate their effort between improving existing fields and inventing new ones. A key assumption is that scientists derive utility from recognition from other scientists. We show that the economy can be either in a regime where new fields are constantly invented, and then converges to a steady state, or in a cyclical regime where periods of innovation alternate with periods of exploitation. Our analysis provides a rigorous foundation to the Kuhnian theory of scientific evolution. We show that scientists' care for reputation has a strong impact on research dynamics and tends to favor innovation. Especially, innovation fads may emerge. We also study welfare and find that the academic reputational reward system can help align scientists' short-term incentives with society's long-term interests. 相似文献

Abstract This paper presents a selective survey of the recent literature on labour market institutions and offers new empirical EU‐based evidence on the impact of labour market reforms on employment and labour market adjustment. Although the literature traditionally treats labour market institutions as exogenous, attention shifted recently towards understanding the underlying causes of specific institutional arrangements. As a consequence, the literature highlights the great importance of an efficient policy design exploiting these interactions wisely and identifies general principles for achieving an efficient policy design at both macro and micro levels. Although empirical evidence does not show a major change in terms of intensity of labour market reform after the setting of the Economic and Monetary Union and the creation of the euro, the reforms aiming at strengthening the labour market attachment of vulnerable groups tend to have been successful both in raising their employment and increasing labour market adjustment. 相似文献
