Many small firms in Sweden are characterized by a lack of equity capital. For several years measures to increase the equity capital have been discussed. In this discussion the private investors' market has received virtually no attention. This study presents some preliminary results of the private investors in Sweden. The research in small firms financing is characterized by a lack of theoretical framework. One basic assumption in the study is that agency theory can provide an essential framework to explain the interaction between the private investor and entrepreneur. Twenty-five hypotheses generated from agency theory are formulated and tested on 62 small unlisted firms in Sweden. Multiple regression analysis is used for the causal analyses. The empirical results in the study show inter alia that the geographic distance and the private investor's knowledge about the portfolio firm's transformation process seem to be the most influential factors for determining the private investor's involvement in the portfolio firms. It is also interesting to notice that none of the variables, frequency of contacts and the private investor's operational work in the portfolio firm affect the performance of the firm. Contrary to conventional wisdom, private investors do not add value to their portfolio firms through their interaction with the entrepreneurs. The theoretical conclusion is that agency theory does not provide any satisfactory framework to explain the private investor - entrepreneur relationship. Some of the basic assumptions in agency theory seem to be invalid. A model for the relationship between private investors and entrepreneurs is developed in which four interaction strategies are identified. The model gives implications on two levels: the portfolio level and the individual case level. 相似文献

In this paper we examine the impact of tax contracts as a novel institution on elections, policies, and welfare. We consider a political game in which three parties compete to form the government and voters may behave strategically. Parties have policy preferences about the level of public-good provision and benefit from perks when in office. A government raises taxes for both purposes. We show that tax contracts yield moderate policies and lead to lower perks by avoiding the formation of grand coalitions in order to win government. Moreover, in polarized societies they unambiguously improve the welfare of the median voter. 相似文献

Traffic distributions of air traffic and their concentration have been measured through Gini, an index that contrasts in many ways with other more established ones, such as Herfindahl's. This research is extended in the sense that it perceives spatial concentration in air transport as an aggregate of complex networks that are subject to multiple constraints, such as geopolitics or technology. We propose a multi-layered analytic approach where network operators are economic agents that behave in strategic ways. It allows for comparing air traffic between airports in Europe with that of the US and, in particular, introduces a normative component by isolating patterns in airlines' strategies that coincide with more or less welfare-oriented degrees of spatial concentration in light of the above constraints. 相似文献

This paper considers the implementation of a nonstationary, heterogeneous Markov model for the analysis of a binary dependent variable in a time series of independent cross sections. The model, previously considered by M offitt (1993), offers the opportunity to estimate entry and exit transition probabilities and to examine the effects of time-constant and time-varying covariates on the hazards. We show how ML estimates of the parameters can be obtained by Fisher's method-of-scoring and how to estimate both fixed and time-varying covariate effects. The model is exemplified with an analysis of the labor force participation decision of Dutch women using data from the Socio-economic Panel (SEP) study conducted in the Netherlands between 1986 and 1995. We treat the panel data as independent cross sections and compare the employment status sequences predicted by the model with the observed sequences in the panel. Some open problems concerning the application of the model are also discussed. 相似文献

This paper outlines and analyses the major changes in work-force organization that have been introduced by British and German steel producers in the past decade, against a backcloth of retrenchment in the industry, new product development and technological change. Including multiskilling, a reduction in demarcation and team–working, these changes have had a major effect upon the composition of the work–force and the nature of work undertaken at the shopfloor level. While these changes have had a common broad trajectory, they have been introduced at a different pace and in different forms. The contrasts are provided not only at the international level, but between plants in the same countries. The paper further outlines the response of trade unions to these changes and the implications for industrial relations at the shopfloor level. 相似文献

Abstract We consider two models in which the logarithm of the price of an asset is a shifted compound Poisson process. Explicit results are obtained for prices and optimal exercise strategies of certain perpetual American options on the asset, in particular for the perpetual put option. In the first model in which the jumps of the asset price are upwards, the results are obtained by the martingale approach and the smooth junction condition. In the second model in which the jumps are downwards, we show that the value of the strategy corresponding to a constant option-exercise boundary satisfies a certain renewal equation. Then the optimal exercise strategy is obtained from the continuous junction condition. Furthermore, the same model can be used to price certain reset options. Finally, we show how the classical model of geometric Brownian motion can be obtained as a limit and also how it can be integrated in the two models. 相似文献
