The relationship between unemployment and self-employment has been studied extensively. Due to its complex, multifaceted nature, various scholars have found a large array of different results, so that the exact nature of the relation is still not clear. An important element of the relation is captured by the recession-push hypothesis which states that in times of high unemployment individuals are pushed into self-employment for lack of alternative sources of income such as paid employment. We make two contributions to this literature. First, we argue that official unemployment rates may not capture the ??true?? rate of unemployment as it does not include ??hidden?? unemployed who are out of the labour force. Therefore, we propose a new method where the ??recession-push?? effect relates not only to the (official) unemployed but also to the inactive population. Second, we argue that the magnitude of the recession-push effect is non-linear in the business cycle, i.e. the effect is disproportionally stronger when economic circumstances are worse. We provide empirical support for our hypotheses by estimating an econometric model on Spanish data.  相似文献

We analyze binary choices in a random utility model assuming that agent’s preferences are affected by conformism (with respect to the behavior of the society) and coherence (with respect to identity). We show that multiple stationary equilibria may arise and that the outcome looks very different from a society where all the agents take their decisions in isolation. We quantify the fraction of agents that behave coherently. We apply the analysis to sequential voting when voters “like to win”. Compared to the present literature, we enrich the setting assuming that each voter is endowed with an ideology and we consider the interplay between coherence and the desire to vote with the (perceived) majority.  相似文献

We analyze the optimal capital structure of a bank issuing countercyclical contingent capital, i.e., notes to be converted into common shares in poor macroeconomic conditions. A comparison of the main effects produced by the countercyclical asset with the simple equity-debt capital structure, the non-countercyclical contingent capital and the countercyclical callable bond is conducted. We demonstrate that this type of asset reduces the spread of straight debt and is effective in reducing the asset substitution incentive. The reduction of bankruptcy costs is strong only when the countercyclicality feature is removed. Contingent capital is useful for macroprudential regulation and we show that the countercyclical feature is important depending on priorities (moderate the asset substitution incentive or reduce bankruptcy costs).  相似文献

The analysis of technological change is centered on the study of the evolution of technical coefficients in the input–output table. Complementary to this analysis, the household consumption expenditure matrix, relating consumption by commodities to consumption by purpose or by function, also incorporates some other aspects of technological change. Thus, the evolution in time of the coefficients of this consumption expenditure matrix will portray technological processes, implying substitutions between commodities to satisfy the different functions The substitution between consumption expenditure by functions is also to be taken into consideration, because it can influence, together with technological change, the use of commodities in the final demand. For Switzerland, a 1980–89 time series of household consumption expenditure matrices with 37 commodities and 58 functional consumption categories has been estimated using data from consumer expenditure surveys. In this paper, instruments generally applied to the analysis of changes in input–output technical coefficients are extended to these matrices, including methods that deal with biproportional processes of substitution.  相似文献

We combine agency theory with the law and finance approach to analyze how the legal protection of investors and the corporate ownership structure affect corporate investment in research and development (R&D). We use information from 956 firms from the five most R&D-intensive industries in 19 developed countries. Our results show that better protection of investors’ rights by the institutional environment has a positive influence on corporate R&D. We also find that corporate ownership concentration works as a substitute for legal protection. This finding means that R&D investment of the firms in the countries with poor legal protection increases as ownership becomes more concentrated. Our results also show that the identity of shareholders has a relevant effect: Whereas banks and nonfinancial institutions as shareholders result in lower R&D, institutional investors as shareholders increase corporate investment in R&D.  相似文献

We study the dynamic impact of recycling through its effect on the production set of the economy and its relationship with natural resources. The contribution of renewable and recyclable resources for sustainability is studied. Although in the short run recycling may alleviate resource scarcity, in the long run it is not enough to compensate for the exhaustibility of non-renewable resources and the possibility of obtaining non-decreasing output paths crucially depends on the extent to which production rests on renewable resources. Furthermore, recycling interacts with natural resource growth, surprisingly not always favoring sustainability. The Production and Recycling Function is a generalization of the traditional production function, providing an integrated view of regular production and recycling and representing the production set of the economy when a recycling technology is available.  相似文献

A kernel-based method for nonparametric estimation of variograms   总被引:2,自引:0,他引:2  
Variogram estimation plays an important role in many areas of spatial statistics. Potential areas of application include biology, ecology, economics and meteorology. However, it is common that, for example under highly correlated patterns, traditional estimators can not reflect all the spatial features or dependencies. In this paper, we present an alternative distribution-free estimator based on nearest-neighbour estimation with a non-constant smoothing field that is better able to adapt to spatially varying features of the data pattern. We present a simulation study to compare our new estimator to a nearest-neighbour estimator built with a constant smoothing parameter and to the classical variogram estimator. We apply our method to analyze two ecological data sets.  相似文献

Exploring different views of exchange rate regime choice   总被引:1,自引:0,他引:1  
The empirical distinction between de facto and de jure exchange rate regimes raises a number of interesting questions. Which factors may induce a de facto peg? Why do countries enforce a peg but do not announce it? Why do countries “break their promises”? We show that a stable socio-political environment and an efficient political decision-making process are a necessary prerequisite for choosing a peg and sticking to it, challenging the view that sees the exchange rate as a commitment device. Policymakers seem rather concerned with regime sustainability in the face of adverse economic and socio-political fundamentals.  相似文献

The paper studies the motivations behind banks’ shareholding of non-financial firms using a panel of large Italian companies in the period 1994–2000. Empirical evidence shows that banks are shareholders of companies that are less profitable, have experienced slower growth, are more indebted, are endowed with collateral and have hard time to repay their debt out of current income. Banks are more likely to hold shares in companies they lend to. Overall the evidence suggests that there is complementarity between bank equity holding and lending. A plausible explanation is the shareholder–debtholder conflict, the evidence is weakly compatible with governance and information hypotheses.  相似文献
