This paper examines the competitive characteristics of U.S. manufacturers in the machine tool (MT) industry. After several decades of decline, this industry has recently shown signs of a modest but sustained recovery. Empirical evidence from a national survey of 104 MT producers suggests that the revival of this sector has been driven by a combination of factors, including renewed export involvement, improved customer support, and better product design. Although most MT companies are small-to-medium-sized enterprises (SMEs), the survey data show that very small SMEs are poorly represented in the recovery thrust of the industry as a whole. Our principal conclusion is that the MT industry has been following an export-led path toward stabilization, but that certain types of small producers are unlikely to thrive for very long. The most serious problems facing small producers include shrinking local markets, import competition, shortages of skilled labor, and cyclical demand. 相似文献

The present study empirically examines the contribution of the acquired banks in only the nonconglomerate types of mergers
(i.e., banks with banks), where the bulk of the payment is in the form of equity to the acquiring bank and finds overwhelmingly
statistically significant evidence that nonconglomerate types of mergers definitely reduce the total as well as the unsystematic
risk while having no statistically significant effect on systematic risk. Therefore, it seems that diversification may be
a possible motive for bank mergers. 相似文献

We examine how the different mix of informed and liquidity trading in the market for ETFs affects the nature of inter-market
competition. We find that both the characteristics of the securities and the structures of the competing markets jointly determine
the nature of inter-market competition. Given the superior execution quality on the ECNs and the low adverse selection costs
in the ETF market, anonymous market such as the ECNs, attract both liquidity and informed traders. We also find that markets
compete in a subset of ETFs. In addition, we find that quotebased competition is prevalent in the market for ETFs. 相似文献

Zusammenfassung Es wird eine optimale Strategie im Sinne des minimalen erwarteten Verlustes für die beiden Entscheidungeny>y
o undyy
o aufgrund der Messungen einer mitY positiv korrelierten, einfacher und/oder billiger zugänglichen ZufallsvariablenX abgeleitet. Dabei wird angenommen, daßX undY nach einer bivariaten Normalverteilung mit bekannten Parametern verteilt sind und die Entscheidungyy
o getroffen wird, wennx größer ist als ein zu bestimmendesx
o, und die Entscheidungy>y
o, wennx gleich oder kleiner als diesesx
o ist. Für die Bestimmung des optimalenx
o werden zunächst die Kosten für die beiden Fehlentscheidungen jeweils als konstant vorausgesetzt, in einem weiteren Ansatz wird jedoch für die Mißklassifikationyy
o eine mity exponentiell wachsende Risikofunktion angenommen. Um die relative Häufigkeit der zu erwartenden Fehlklassifikationen abschätzen zu können, wird schließlich die bedingte WahrscheinlichkeitP(x>x
o,y) errechnet.
Summary An optimal strategy, with minimum expected risk, for the decisionsy>y o oryy o is constructed on the basis of the measurement of a variableX, which is positively correlated withY and can be measured more easily and/or with smaller expense. A bivariate normal distribution with known parameters is assumed forX andY. For the observationsx a limitx o is aimed at, so that the decisionsy>y o oryy o are taken ifx>x orxx o respectively. Optimal values ofx o are first calculated under the assumption of constant losses for the two misclassifications (x>x o ifyy o andxx o ify>y o). In a further approach the loss for a wrong decisionyy o is assumed to increase exponentially withy. Finally the conditional probabilityP (x>x o\y) is calculated to get an assessment of the relative frequencies of wrong decisions to be expected.相似文献

This article develops a new method of estimating inefficiencies in joint production and shows that unlike the approaches utilized in the previous studies of inefficiency, this method maintains a consistent relationship between the error term of a profit function and the error terms of its price derivatives. A useful by-product of the method is a proof of a Hotelling-like lemma that relates stochastic input demand and output supply functions to stochastic profit functions. While the previous studies fit a single frontier to data on all firms, this paper estimates a frontier unique to every observed firm to allow each one to have a different potential of achieving maximal levels of profit. The new method is applied in the analysis of annual data, 1984–1989, for U.S. commercial banks. Both the analytical and numerical results of the paper show that the residual that the previous studies attribute to inefficiency includes the effects of excluded variables and of inaccuracies in the specified functional forms. Once accurate estimates of these effects are subtracted from the residual, the distortions in the measured inefficiencies should be considerably reduced. Consequently, this article considers how such estimates might be obtained. 相似文献

The authors analyze the relationship between labor force participation and fertility in Canada using data from the Public Use Sample Tapes from the 1971 and 1981 censuses. Factors considered include age, religion, educational status, and marital status. The authors conclude that "labour force participation of women seems to have less influence on fertility compared to [the] fertility effect on labour force participation." 相似文献
