Summary. We discuss a competitive (labor) market where firms face capacity constraints and individuals differ according to their productivity.
Firms offer two-dimensional contracts like wage and task level. Then workers choose firms and contracts. Workers might be
rationed if the number of applicants exceeds the capacity of the firm.
We show that under reasonable assumptions on the distribution of capacity an equilibrium in pure strategies (by the firms)
exists. This result stands in contrast to the case of unlimited capacity. The utility level is uniquely determined in equilibrium.
No rationing occurs in equilibrium, but it does off the equilibrium path.

Even though Germany’s economy is currently going strong, the country still faces enormous challenges if it wants to maintain and increase this prosperity. The new government should take this opportunity to set the course for the future by encouraging the digitalisation of the economy and the society as well as by ensuring that the ongoing energy transition is sustainable and efficient. Other challenges include the adverse effects of globalisation on parts of society and the uneven distribution of income and wealth. But the actual magnitude of the government’s room to manoeuver is up for debate. The new government’s fiscal space might be more limited than it seems, since an automatic adjustment of the income tax to inflation and growth is required to end the bracket creep. Given that transfer programmes are being phased out, the federal income tax surcharge to finance German unification also needs to be abolished. Further budget pressure stems from the pension system and from demands by state and local as well as European governments. The new German government should use the next governing period to initiate fundamental reforms of economic and fiscal policy that will provide adequate answers to long-run challenges. 相似文献

This article develops theory about an agency problem affecting the strategic human capital (SHC) of the firm. It proposes three categories of SHC‐related choices managers must make that imply a trade‐off between near‐ and long‐term performance. Dispersed shareholding, firm coverage by securities analysts, and their practice of publishing quarterly earnings forecasts are argued to entail a bias in management incentives, shifting the balance in this trade‐off toward near‐term performance. To restore the balance, securities analysts would need to distinguish transitory from recurring effects of SHC‐related choices in their valuation models (e.g., treating certain labor cost savings during cyclical downturns as transitory). Restoring the balance would also require them to anticipate long‐term effects in their long‐term earnings forecasts (e.g., long‐term positive effects of retaining employees with valuable skills during cyclical downturns). The article discusses specific transitory cost effects and long‐term effects they could potentially take into account. The skills and incentives needed by analysts to account for such effects are argued to vary across firm segments. 相似文献

A Time to Scatter Stones,and a Time to Gather Them: The Annual Cycle in Hedge Fund Risk Taking 下载免费PDF全文
Analyzing a sample of hedge fund daily returns from Bloomberg, we find a seasonal pattern in their risk taking. During earlier months of a year, poorly performing funds reduce risk. The reduction is stronger for funds with higher management fees, shorter redemption periods, and recently deteriorating performance, consistent with a managerial aversion to early fund liquidation. Toward the end of a year, poorly performing funds gamble for resurrection by increasing risk. It is largely achieved by increasing exposure to market factors, and can be linked to stronger indirect managerial incentives during the second half of a year. 相似文献

A key aim of the ninth revision of the German Act against Restraints of Competition (GWB), intended to come into effect at the end of 2016, has been to address the current economic development induced by digitisation. Digitisation has the potential to become one of the most challenging developments for both competition policy and economic policy. This article evaluates the adequacy of the revision based on an economic analysis of the evolving market structures. These include two-sided markets and network effects, which require revision of the criteria for the evaluation of competition in markets. In addition, this article discusses the effects of the sharing economy on existing market structures, and the necessity to establish an appropriate regulatory framework and to eliminate possible market failures. 相似文献

We develop a model in which firms in the financial market lobby the government to lower compulsory contributions to the public pension system. Firms lobby in order to increase demand from households for their old-age savings products. We conclude with a comparison of two major pension reforms in Europe exemplifying the influence of financial market lobbies on pension policies. 相似文献
