abstract    We apply the resource-based view of the firm to the study of family firms by investigating how a family specific resource (reciprocal altruism) and a firm specific resource (innovative capacity) contribute to family firm performance. We then examine how the impact of these resources is moderated by strategic planning and technological opportunities. Our findings suggest that family firms can benefit from emphasizing the positive aspects of kinship and from developing innovative capacities. As such, we demonstrate that not only do firm specific resources contribute to family firm performance, but also that family relationships can be a source of competitive advantage for a family firm. In addition, we found a heightened importance of reciprocal altruism in environments rich in technological opportunities, and that strategic planning is more important for those family firms that lack innovative capacities.  相似文献

Okun’s (1962) seminal paper is an important study on economic growth and unemployment but a detailed exploration of the effect of productivity growth on unemployment has been left aside. Yet, the relationship between productivity growth and unemployment has been debated since long. In this paper we present stylized facts on the link between productivity growth and unemployment for the short and long run, and present model variants that demonstrate that in the short run productivity growth may increase unemployment while in the long run the relationship between productivity growth and unemployment are likely to co-vary negatively. Using US data, empirically we decompose the time series of unemployment rate and productivity growth into long run and short run components and show empirical evidence that the long run and short run components co-vary as predicted by some theories.  相似文献

Growth Effects of Fiscal Policy and Debt Sustainability in the EU   总被引:3,自引:0,他引:3  
In this paper we study the relationship of fiscal policy and economicperformance of some core countries in the EU. Our aim is to find outwhether public deficit and public debt have consequences for real variables in the economies we consider. The background of our empirical study is a growth model that provides us with some predictions on the relationship between fiscal policy and economic growth. In a first step we then use Granger causality tests to analyze empirically whether some of the implications of our model arecompatible with the data. In a second step, we investigate whether the fiscalpolicies of the member states have been sustainable. Given this information,we then pursue the question of whether differences in the fiscal positions ofcountries have consequences as concerns the outcome of our empirical testsof step one. Finally, we study whether the impact of the public deficit ratiodepends on the magnitude of the debt ratio.  相似文献

By contrasting endogenous growth models with facts, one is frequently confronted with the prediction that levels of economic variables, such as R&D expenditures, imply lasting effects on the growth rate of an economy. As stylized facts show, the research intensity in most advanced countries has dramatically increased, mostly more than the GDP. Yet, the growth rates have roughly remained constant or even declined. In this paper we modify the Romer endogenous growth model and test our variant of the model using time series data. We estimate the market version both for the US and Germany for the time period January 1962 to April 1996. Our results demonstrate that the model is compatible with the time series for aggregate data in those countries. All parameters fall into a reasonable range.  相似文献

Summary. The paper studies creditworthiness in a model with endogenous credit cost and debt constraints. Such a model can give rise to multiple candidates for steady state equilibria. We use new analytical techniques such as dynamic programming (DP) with flexible grid size to find solutions and to locate thresholds that separate different domains of attraction. More specifically, we (1) compute present value borrowing constraints and thus creditworthiness, (2) locate thresholds where the dynamics separate to different domains of attraction, (3) show jumps in the decision variable, (4) distinguish between optimal and non-optimal steady states, (5) demonstrate how creditworthiness and thresholds change with change of the credit cost function of the debtor and (6) explore the impact of debt ceilings and consumption paths on creditworthiness.JEL Classification Numbers: C61, C63, D91, D92, E51, G12, G32.An earlier version of this paper has been prepared for the 1998 North American Winter Meeting of the Econometric Society, January 1998, Chicago.

Abstract

Although the consumption based asset pricing theory appears to be theoretically superior and more elegant than the beta pricing model, in practice the beta pricing model is more widely applied. Indeed, beta pricing models are one of the most widely adopted tools in financial analysis. They readily allow handling systematic risk as priced in financial assets. However, accurately estimating beta-coefficients is not as straightforward as implicitly suggested by Sharpe's standard market model, i.e. simply using the ordinary least-squares (OLS) regression. This is primarily because beta-coefficients cannot generally be assumed to be stable over time. In order to overcome this deficiency, we present and apply a non-parametric estimation technique that allows capturing this time effect and promises both more reliable estimates than obtained with an OLS regression as well as better manageability compared with the existing time-series approaches dealing with time-varying beta-coefficients. Estimation results for constant and time-varying betas are presented for portfolios of German industries.  相似文献

With rapidly rising government debt and ageing populations implying high contingent liabilities in public pension systems, the issue of longer-term fiscal developments is gaining importance. The question arises whether, and to what extent, future generations will be burdened by current policies. Generational accounting is a new approach to examining such issues and it is used more and more in the policy debate.  相似文献
