Strategic alliances,organisational learning and new product development: the cases of Rover and Seat

The importance of the automotive industry in the global economy is widely recognised. The sector has undergone enormous changes in order to prepare for the fierce competition of the 21st century. Among these transformations, the most relevant are those technologies developed for the rapid evolution of activities linked to new designs, new products, and new manufacturing processes and systems. Innovative Japanese carmakers have stimulated international performance comparisons in these activities. International technology alliances may be one way of gaining access to new competitive technologies. Risks and costs associated with new product development can be shared among the partners and more effective use can be made of manufacturing facilities and production capabilities. Sometimes, an alliance agreement may lead to the deployment of new capabilities. However, in spite of this potential, the literature presents the success rate of alliances at less than 50%. Our study considers two examples of companies that developed international joint ventures (IJVs): Rover with Honda, and Seat with Volkswagen. Since these two European peripheral companies, Rover and Seat, no longer remain as independent firms, we are interested in identifying the reasons leading to the success or failure of these IJVs as regards the New Product Development (NPD) process. In particular, in both cases the paper looks at the problems of the weaker partner becoming increasingly dependent on the other partner and the need for a well-defined strategy to benefit from IJVs.     

Love,hate and murder: Commitment devices in violent relationships

Many violent relationships are characterized by a high degree of cyclicality: women who are the victims of domestic violence often leave and return multiple times. To explain this we develop a model of time inconsistent preferences in the context of domestic violence. This time inconsistency generates a demand for commitment. We present supporting evidence that women in violent relationships display time inconsistent preferences by examining their demand for commitment devices. We find that no-drop policies – which compel the prosecutor to continue with prosecution even if the victim expresses a desire to drop the charges – result in an increase in reporting. No-drop policies also result in a decrease in the number of men murdered by intimates suggesting that some women in violent relationships move away from an extreme type of commitment device when a less costly one is offered.     

Returns to education and wage equations

The paper shows why considering a number of education-dependent covariates in a wage equation decreases the coefficient of education in that equation. This result is illustrated empirically with a meta-analysis for Portugal. The education coefficient decreases when covariates are used that can be considered post-education decisions; on the other hand, it is independent of sample size, tenure and whether hourly or monthly wages are used. These results support the use of a simple specification of the Mincer equation for the study of the total returns to education.     

Contingent Valuation: Controversies and Evidence

Contingent valuation (CV) has become one of the most widely usednon-market valuation techniques. CV's prominence is due to itsflexibility and ability to estimate total value, includingpassive use value. Its use and the inclusion of passive use valuein benefit-cost analyses and environmental litigation are thesubject of a contentious debate. This paper discusses key areasof the debate over CV and the validity of passive use value. Weconclude that many of the alleged problems with CV can beresolved by careful study design and implementation. We furtherconclude that claims that empirical CV findings are theoreticallyinconsistent are not generally supported by the literature. Thedebate over CV, however, has clarified several key issues relatedto nonmarket valuation and can provide useful guidance both to CVpractitioners and the users of CV results.     

Expectational coordination in simple economic contexts

We consider an economic model that features (1) a continuum of agents and (2) an aggregate state of the world over which agents have an infinitesimal influence. We first review the connections between the ??eductive?? viewpoint on expectational stability and standard game-theoretical rationalizability concepts. The ??eductive?? reasoning selects different plausible beliefs that are a priori, and possibly a posteriori, ??diverse??. Such beliefs are associated with the sets of ??Cobweb tatonnement?? outcomes, ??Rationalizable States?? and ??Point-Rationalizable States?? (the latter two being shown to be convex). In the case where our model displays strategic complementarities, unsurprisingly, all our ??eductive?? criteria support similar conclusions, particularly when the equilibrium is unique. With strategic substitutabilities, the success of expectational coordination, in the case where a unique equilibrium does exists, relates with the absence of cycles of order 2 of the ??Cobweb?? mapping: in this case, full expectational coordination would be achieved. However, when cycles of order 2 do exist, our different criteria predict larger sets of outcomes, although all tied with cycles. Under differentiability assumptions, the Poincaré?CHopf method leads to other global stability results. At the local level, the different criteria under scrutiny can be adapted. They lead to the same expectational stability conclusions, only when there are local strategic complementarities or strategic substitutabilities. However, for the local stability analysis, it is demonstrated that the stochastic character of expectations can most often be forgotten.     

The effect of social security,health, demography and technology on retirement

This article studies the determinants of the labor force participation of the elderly and investigates the factors that may account for the increase in retirement in the second half of the last century. We develop a lifecycle general equilibrium model with endogenous retirement that embeds Social Security legislation and Medicare. Individuals are ex ante heterogeneous with respect to their preferences for leisure and face uncertainty about labor productivity, health status and out-of-pocket medical expenses. The model is calibrated to the U.S. economy in 2000 and is able to reproduce very closely the retirement behavior of the American population. It reproduces the peaks in the distribution of Social Security applications at ages 62 and 65 and the observed facts that low earners and unhealthy individuals retire earlier. It also matches very closely the increase in retirement from 1950 to 2000. Changes in Social Security policy – which became much more generous – and the introduction of Medicare account for most of the expansion of retirement. In contrast, the isolated impact of the increase in longevity was a delaying of retirement.     

How a Reduction of Standard Working Hours Affects Employment Dynamics

December 1, 1996 a new law was implemented in Portugal to gradually reduce the standard workweek from 44 to 40 h. We study how this mandatory reduction affected employment through job creation and job destruction. There was considerable regional, sectoral and firm-size variation in the share of workers who were affected by the working hours reduction. We exploit this variation to assess the impact of the workweek reduction. We find evidence that the working hours reduction had a positive effect on employment through a fall in job destruction.     

Two Trees

We solve a model with two i.i.d. Lucas trees. Although the correspondingone-tree model produces a constant price-dividend ratio andi.i.d. returns, the two-tree model produces interesting asset-pricingdynamics. Investors want to rebalance their portfolios afterany change in value. Because the size of the trees is fixed,prices must adjust to offset this desire. As a result, expectedreturns, excess returns, and return volatility all vary throughtime. Returns display serial correlation and are predictablefrom price-dividend ratios. Return volatility differs from cash-flowvolatility, and return shocks can occur without news about cashflows.
