In this article I explain why asset‐based fees are common for mutual fund management companies and why the average fee has increased recently. I argue that Securities and Exchange Commission fee regulations make alternative fee types illegal or unattractive. Management companies can maintain higher fees because regulations and brand‐name capital partly insulate them from competition and because investors cannot easily distinguish between performance‐oriented and marketing‐oriented fund companies. Index funds and unit investment trusts may offer competition to mutual funds in the future because they are designed to minimize management fees. 相似文献

Summary Standard laboratory posted-offer markets respond slowly and incompletely to demand shocks. In these one-sided markets, where sellers control the setting of prices, very little information is transmitted via the process of exchange. For this reason, traders have trouble distinguishing randomness in their own experience from changes in market fundamentals. This paper reports the results of twelve laboratory markets conducted to assess whether some common variants to standard posted-offer rules can correct the adjustment deficiences. Although discounting, multiple postings and excess demand information all improve performance, we find that response remains poor, and efficiencies low.Support for this research was provided by the National Science Foundation (SBR 9319842 and SBR 9320044), and the University of Virginia Bankard Fund.

A firm employs suppliers who make specific investments. Because output demand is uncertain and the cost of enumerating contingencies high, the firm retains some unilateral control over the input quantities it purchases. To allay suppliers’ concerns over potential opportunism the firm must commit not to pit them against one another ex post by threatening to buy less from those who refuse to discount their prices. By extending most-favored treatment guarantees the firm commits not to discriminate. In some circumstances this generates efficient and opportunism-free outcomes. In others it is less effective but may remain attractive relative to other options. Evidence from field market contracts for natural gas corroborates this nondiscrimination hypothesis. 相似文献

Abstract. I evaluate a new German regulation that requires retail discounters to guarantee the availability of their products in bargain sales. The regulation is meant to prevent loss leaders. Retailers undermine the regulation's rationale by claiming that rationing is due to demand uncertainty. This paper shows that under demand uncertainty the regulation has ambiguous welfare effects. Effectively, it raises production, which, under imperfect competition, tends to be beneficial. However, the regulation overshoots and decreases welfare if it requires availability for a state of high demand that is relatively unlikely. In this case more sophisticated regulation is required. 相似文献

Abstract. We use parametric power ARCH models of the conditional variance of inflation to model the relationship between inflation and its uncertainty using monthly data for Germany, the Netherlands and Sweden over a period ranging from 1962 to 2004. For all three countries inflation significantly raises inflation uncertainty as predicted by Friedman. Increased uncertainty affects inflation in all countries but not in the same manner. For Sweden we find a negative impact in accordance with the Holland hypothesis, whereas for Germany and the Netherlands we find the opposite in support of the Cukierman–Meltzer hypothesis. In a sensitivity analysis we show that an arbitrary choice of the heteroscedasticity parameter influences this relationship significantly. 相似文献

There is a robust literature on the relationship between financing constraints and real investment. Little has been said on the relationship between financing constraints and capital stock in the long run. This note focuses on this last issue. To keep the model tractable, we assume that the firm employs a single input, and this input is used as collateral. We get three main results. Firstly, we show that the optimal capital stock chosen by a firm is affected by financing constraints even when they are slack at the current time. Secondly, we show that the net present value of the potentially constrained firm is always smaller than the one of the never constrained firm. Finally, we find that in the presence of latent financing constraints the firm does not limit itself to reducing its investment when the upper limit is reached. What it actually does is to lower its long run optimal capital stock, amplifying the effects of constraints in the long run. 相似文献

Two of the main forces driving European emigration in the late nineteenth century were real wage gaps between sending and receiving regions and demographic booms in the low‐wage sending regions. Our new estimates of net migration for the countries of sub‐Saharan Africa show that exactly the same forces driving African across‐border migration are at work today. The results suggest that rapid growth in the cohort of potential young emigrants, population pressure on the resource base, and slow economic growth are likely to intensify the pressure for migration out of Africa and into high‐wage OECD countries over the next two decades. 相似文献

This paper analyzes the origins and welfare consequences of buyer power. We show that if suppliers are capacity constrained or have strictly convex costs, there are two different channels through which large buyers can obtain more favorable terms from their suppliers. In particular, we show how the presence of large buyers can then erode the value of suppliers’ outside option. Somewhat surprisingly, we show how this can induce suppliers to undertake strategies that lead to higher output and potentially higher welfare. 相似文献

We examine the stock market reaction to 1227 inter-corporate ordinary business contract announcements reported by Dow Jones between January 1, 1990 and December 31, 2001. Around contract announcement dates, we find statistically significant positive average abnormal returns and abnormal trading volume for contractors, but insignificant positive abnormal returns and negative abnormal volume for contractees. Cross-sectionally, contract announcement period returns are higher for contractors who are small relative to the contract size, have higher return volatility, larger market-to-book ratios and higher profitability. The announcement period returns of contract-awarding firms are not significant and are only marginally related to cross-sectional explanatory factors. The results are consistent with two explanatory stories: contractor quasi-rents induced by the winner's curse and information signalling about contractor production costs. The results are not consistent with perfect competition, with contracts having positive net present values for both parties, and with a version of incomplete contracting theory. 相似文献

Concerning industrial location, the home market effect (HME) predicts that a large country is a net exporter of industrial goods. Recent literature shows that high transport costs in the traditional sector may obscure the HME in an early model of two sectors à la Helpman and Krugman. This paper presents an alternative model that displays the relationship between the HME and arbitrary transport costs while allowing for the derivation of analytical results by simple algebra. Our results show that the transport costs in the traditional sector do not obscure the HME but constitute a dispersion force that decreases the impact of the HME. 相似文献
