This paper studies the duration of two cohorts of entrants in the Italian financial intermediation industry. Using the Cox
(1972) Proportional Hazards Model, it analyses the link between duration of each newborn firm and its start-up size, as well
as a series of industry-specific characteristics. It emerges that not only did regulatory reform in 1990 result in a process
of branch proliferation and industry concentration, but it also set in motion a pre-entry selection mechanism. Conversely,
before completion of the regulatory reform, in 1989, entry was possible even for very small firms, and larger new entrants
survived longer than their smaller counterparts, and this independently of the features of spatial and structural competition.

Uncertainty and entry deterrence 总被引:3,自引:0,他引:3
Eric S. Maskin 《Economic Theory》1999,14(2):429-437
Summary. We study a model where capacity installation by an incumbent firm serves to deter others from entering the industry. We argue
that uncertainty about demand or costs forces the incumbent to choose a higher capacity level than it would under certainty.
This higher level diminishes the attractiveness of deterrence (Proposition 1) and, therefore, the range of parameter values
for which deterrence occurs (Proposition 2).

This paper discusses the entrepreneurial landscape in Africa and locates a new generation of African entrepreneurs and their business networks within it. Unlike others in that landscape (i.e. micro- or small-scale informal sector vendors, and traditional or multinational large-scale formal sector firms), the ‘new generation’ entrepreneurs are business globalists who organized a system of business enterprise networks consisting of national, regional, and pan-African organizations. The study analyses interview data from 57 men and women network members from 10 countries (Botswana, Ethiopia, Ghana, Kenya, Mali, Senegal, South Africa, Uganda, Zambia, and Zimbabwe). Some defining characteristics of these entrepreneurs are interactive social and business relationships, use of modern management methods and information technology, trust among fellow members, transparent business practices, advocacy on behalf of the private sector, and commitment to increasing intra-African commerce. Their mission is to improve the climate for private sector business in Africa and to promote regional economic integration. They pursue cross-national commercial ventures, maintain official observer status at established regional economic organizations, sign memoranda of understanding with multilateral agencies, establish venture capital funds, and help to change government policies. The paper identifies characteristics of the ‘new generation’ entrepreneurs, evaluates goals and achievements of their networks, and concludes that despite limitations, these entrepreneurs and their organizations have created intra- and cross-national networks that strengthen private-sector-led economic growth in Africa. 相似文献

This paper employs daily fund and index data, the classical Treynor and Mazuy timing model, and two multi-factor extensions to measure the market timing ability of global asset allocation funds. These funds differ from traditional global or international funds in that they face fewer investment constraints and are known to actively shift funds across a wide variety of asset classes. When using the classical Treynor and Mazuy timing models, I find evidence of poor market timing ability. However, this evidence disappears when timing ability is examined using two multi-factor models. The results from Treynor and Mazuy are spurious since both multi-factor extensions do a much better job in explaining the variation in average fund returns. 相似文献

This study examines how market timing can affect host market reaction to cross-border seasoned equity offerings (SEOs), an event generally viewed unfavorably by investors. We assume that firms engage in market timing in response to valuation uncertainty (VU), home market uncertainty (HMU) and/or host market uncertainty (HSU), and that raising capital abroad faces higher scrutiny costs and familiarity bias from host market investors. We conjecture that timing strategies provide signals that vary in strength to host market investors and that dual-timing strategies may strengthen an existing signal. Our hypotheses are tested on a sample of 190 cross-border SEOs that were issued on the U.S. stock market between 1990 and 2017 by firms from 29 countries. Using event study methodology, we find that market timing based on VU is negatively related to host market valuation and that a dual-timing strategy with HMU or HSU generally produces a stronger signal. Our results have practical relevance for stock markets that suffer from high uncertainty; we estimate that a high VU firm with a $1 billion valuation suffers a drop of $31.3 million in market valuation during a high host market uncertainty (high HSU) compared with low host market uncertainty (low HSU). 相似文献

What do we know about entry? 总被引:5,自引:0,他引:5
This paper is a brief survey of recent empirical work on entry. It is organized as a series of stylized facts and a series of stylized results which together summarize much of what is generally understood - or believed - about what drives entry, and about the effects that entry has on markets. 相似文献

The entry of new firms into markets plays an important role in efficient resource allocation and evolution for long term economic
growth. Employing dynamic panel data techniques, this paper investigates entry behavior in 66 four-digit Turkish manufacturing
industries for the 1993–1999 period. The results of this paper suggest that potential entrants observe the market before the
entry takes place; entry is, in general, a follow-up process; and incumbent firms seem to collude to prevent entry in Turkish
manufacturing industries. In addition, the real interest rate appears to be a very important determinant of entry decision. 相似文献

Several explanations for the observed limited stock market participation have been offered in the literature. One of the most promising is the presence of market frictions mostly in the form of fixed entry and/or transaction costs. Empirical studies point to a significant structural (state) dependence in the stock market entry decision, which is consistent with costs of this type. However, the magnitude of these costs is not yet known. This paper focuses on fixed stock market entry costs. I set up a structural estimation procedure which involves solving and simulating a life cycle intertemporal portfolio choice model augmented with a fixed stock market entry cost. Important features of household portfolio data (from the PSID) are matched to their simulated counterparts. Utilizing a Simulated Minimum Distance estimator, I estimate the coefficient of relative risk aversion, the discount factor and the stock market entry cost. Given the equity premium and the calibrated income process, I estimate a one-time entry cost of approximately two percent of the permanent component of the annual labor income. My estimated model matches the zero median holding as well as the hump-shaped age–participation profile observed in the data. 相似文献

The purpose of this paper is to analyse entry and exit of establishments in 71 3-digit industries in Dutch manufacturing between 1986 and 1990. A distinction is made between existing firm entry and new firm entry and between general exit and exit by bankruptcy. The incentive effect of profitability and the barrier effect of capital intensity and advertising intensity appear to be stronger for new firm entry than for existing firm entry. Growth and capital intensity turn out to reduce exit by bankruptcy, whereas R&D intensity reduces general exit. The positive impact of general exit on new firm entry and vice versa points to replacement and displacement.An earlier version of this paper was presented at the 21st annual EARIE conference, Crete, Greece, September 4–6, 1994.
