Abstract. During the last decade, many Western economies reformed their welfare systems with the aim of activating welfare recipients by increasing welfare‐to‐work programmes (WTWP) and job‐search enforcement. We evaluate the short‐term effects of three important German WTWP implemented after a major reform in January 2005 (‘Hartz IV’), namely short training, further training with a planned duration of up to three months and public workfare programmes (‘One‐Euro‐Jobs’). Our analysis is based on a combination of a large‐scale survey and administrative data that is rich with respect to individual, household, agency level and regional information. We use this richness of the data to base the econometric evaluation on a selection‐on‐observables approach. We find that short‐term training programmes, on average, increase their participants' employment perspectives. There is also considerable effect heterogeneity across different subgroups of participants that could be exploited to improve the allocation of welfare recipients to the specific programmes and thus increase overall programme effectiveness.  相似文献

We show that some care is needed when inferring true unconditional correlations from observed conditional correlations, which is a frequent problem in empirical finance and elsewhere. We give a general formula for the relationship between the two and demonstrate its importance in the context of the bivariate t-distribution.  相似文献

What are the costs and benefits of mandatory dividend rules? On the one hand, they make it harder for controlling shareholders to divert corporate assets. On the other hand, they reduce the internal funds available for firms to invest, possibly leading to the loss of valuable projects. To assess this trade-off, we look at investment and dividend decisions in a sample of public firms in Brazil. We show that a significant fraction of these firms use loopholes of Brazil's mandatory dividend rules to avoid paying dividends. And yet, the dividend rules are effective. They help explain why the average dividend yield in Brazil is higher than in the U.S., without making it harder for firms to invest.  相似文献

As far as economics is concerned, the market for drugs, as in all other cases, maximizes the welfare of all who participate in it, at least in the ex ante sense. Legalization—like the repeal of alcohol prohibition—will also help solve drug related problems such as crime, impurities leading to death and child abuse. Nor does it follow from the fact that such substances are addictive and harmful that using them must be coercive, and should be banned. Also rejected is the ‘public health’ argument that legalization would result in too great a rate of addiction.  相似文献

Abstract

In 1901 the town of Gent appropriated a municipal grant to societies paying benefit to their members in case of unemployment. The decision was founded on a committee report principally written by the lawyer Louis Varlez. The societies should claim individual contributions of the members constituting the right to unemployment allowance under certain conditions. In order to prevent a dissipating risk selection the sphere of activity of a society should join with some society existing before. Such societies had been erected at several places as well in Belgium as in other states, in Gent as early as in 1867. In most cases they were attached to trade unions. It may thus be said that a subsidized unemployment insurance was — for the first time — introduced in Gent 1901. The principles applied are usually called the »Gentsystem». In general accordance with this system state subsidized unemployment insurance was introduced in France 1905, in Norway 1906 and in Denmark 1907. Later several states have established unemployment insurance on a voluntary basis. In modern voluntary state insurance, however, a decisivestress is laid upon the fact that the allowance shall be regulated in accordance with the general rules for public relief of unemployment. Some conditions of the insurance scheme are thus compulsorily laid down in the regulations concerning the subsidy. In some states the unemployment insurance has been wholly established on a compulsory basis. For the first time a compulsory insurance was introduced in England in 1911 covering certain occupational groups. Compulsory unemployment insurance has then been erected in Italy 1919, Poland 1924, Bulgaria 1925 and Norway 1938. In 1938 a law bearing on a change of the voluntary unemployment insurance of Belgium to a compulsory one is being prepared.  相似文献
