The market for publicly traded equity is the heart of a modern capitalist system. In particular, the market for newly listed
firms is in turn a bellwether for the public equity market because the entry gives firms expanded access to capital, allowing
them to emerge and grow. On the other hand, stock markets also serve as an institution to reallocate productive resources
from non-surviving to surviving firms. We describe the Neuer Markt—a special segment of the Frankfurt Stock Exchange in Germany—as an institution to foster the creation of new firms and their
destruction.

This paper analyzes predictive regressions in a panel data setting. The standard fixed effects estimator suffers from a small sample bias, which is the analogue of the Stambaugh bias in time-series predictive regressions. Monte Carlo evidence shows that the bias and resulting size distortions can be severe. A new bias-corrected estimator is proposed, which is shown to work well in finite samples and to lead to approximately normally distributed t-statistics. Overall, the results show that the econometric issues associated with predictive regressions when using time-series data to a large extent also carry over to the panel case. The results are illustrated with an application to predictability in international stock indices. 相似文献

ASYMMETRY OF CUSTOMER LOSS AND RECOVERY UNDER ENDOGENOUS PARTNERSHIPS: THEORY AND EVIDENCE*

This article is inspired by real‐world phenomena that firms lose customers based on imprecise information and take a long time to recover. If consumers are playing an ordinary repeated game with fixed partners, there is no clear reason why recovery happens slowly. However, if consumers are playing an endogenously repeated game, a class of simple efficient equilibria exhibits the asymmetry of fast loss and slow recovery of customers after a bad signal. Exit is systematic, but formation of a new partnership is random. We also give empirical evidence of our equilibria at an individual‐firm level. 相似文献

This paper examines whether gains in bank megamergers occur due to efficiency improvements or the exercise of market power using financial statement line item forecasts from Value Line to infer the effect of the merger on prices and quantities. The average megamerger is associated with cost‐efficiency improvements. In the cross‐section, efficiency gains are limited to market expansion mergers while market overlap mergers and Too‐Big‐To‐Fail (TBTF) mergers exhibit monopoly gains. Efficiency gains dissipate when the resulting megabank size exceeds $150 billion in assets or 1.5% of gross domestic product indicating that banks thought to be TBTF are likely to be “Too‐Big‐To‐Be‐Efficient.” 相似文献

According to most classifications, Sub‐Saharan Africa is the region of the world with the highest presence of fragile states. In this paper we examine the relationship between fragility and poverty, suggesting that countries may become trapped in a vicious circle of fragility and low levels of wellbeing. We consider fragility as a continuum and begin by reviewing available measures. These show the high presence of fragility in Sub‐Saharan Africa and allow the more fragile countries to be identified. There is seen to be a strong association between fragility, poor growth performance, and lower wellbeing in Sub‐Saharan Africa. Building on the strong evidence for the two‐way relationship between economic growth and poverty, we present an analysis of how the vicious circle linking poorer welfare outcomes and fragility may be able to be broken. We argue that building successful institutions is key here, and this can be enabled by specific policy interventions that are both poverty reducing and productive. 相似文献

The mutual fund theorem (MFT) is considered in a general semimartingale financial market S with a finite time horizon T, where agents maximize expected utility of terminal wealth. The main results are:

(i) | Let N be the wealth process of the numéraire portfolio (i.e., the optimal portfolio for the log utility). If any path-independent option with maturity T written on the numéraire portfolio can be replicated by trading only in N and the risk-free asset, then the MFT holds true for general utility functions, and the numéraire portfolio may serve as mutual fund. This generalizes Merton’s classical result on Black–Merton–Scholes markets as well as the work of Chamberlain in the framework of Brownian filtrations (Chamberlain in Econometrica 56:1283–1300, 1988). Conversely, under a supplementary weak completeness assumption, we show that the validity of the MFT for general utility functions implies the replicability property for options on the numéraire portfolio described above. |
(ii) | If for a given class of utility functions (i.e., investors) the MFT holds true in all complete Brownian financial markets S, then all investors use the same utility function U, which must be of HARA type. This is a result in the spirit of the classical work by Cass and Stiglitz. |

Exchanges in Europe are in a process of consolidation. After the failure of the proposed merger between Deutsche Börse and Euronext, these two groups are likely to become the nuclei for further mergers and co‐operation with currently independent exchanges. A decision for one of the groups entails a decision for the respective trading platform. Against that background we evaluate the attractiveness of the two dominant continental European trading systems. Though both are anonymous electronic limit order books, there are important differences in the trading protocols. We use a matched‐sample approach to compare execution costs in Euronext Paris and Xetra. We find that both quoted and effective spreads are lower in Xetra. The differences are more pronounced for less liquid stocks. When decomposing the spread we find no systematic differences in the adverse selection component. Realised spreads, on the other hand, are significantly higher in Euronext. Neither differences in the number of liquidity provision agreements nor differences in the minimum tick size or in the degree of domestic competition for order flow explain the different spread levels. We thus conclude that Xetra is the more efficient trading system. 相似文献
