Entrepreneurial ventures are a key source of innovation. Nowadays, ventures are backed by a wide array of investors whose complementary asset profiles differ significantly. We therefore assert that entrepreneurial ventures can no longer be studied as a homogeneous group. Rather, we harness the inherent dichotomy in the profiles of independent VCs and corporate investors to study ventures' innovation outcomes. Our sample consists of 545 U.S. biotechnology ventures founded between 1990 and 2003 and backed by independent venture capitalists (VCs) or corporate VCs (CVC). We find CVCs' investees exhibit higher rates of innovation output, compared to independent VC‐backed peers. Moreover, the performance of CVC‐backed ventures is sensitive to their ability to leverage corporate assets, underscoring the role of CVC accessibility and FDA approval requirements as the mechanisms associated with CVC contribution.

The objective of this study is to provide a direct estimate of the degree of persistence of measures of nominal and real house prices for the US economy, covering the longest possible annual sample of data, namely 1830–2013. The estimation of the degree of persistence accommodates for non-linear (deterministic) trends using Chebyshev polynomials in time. In general, the results show a high degree of persistence in the series along with a component of non-linear behaviour. In general, if we assume uncorrelated errors, non-linearities are observed in both nominal and real prices, but this hypothesis is rejected in favour of linear models for the log-transformation of the data. However, if autocorrelated errors are permitted, non-linearities are observed in all cases, and mean reversion is found in the case of logged prices, though given the wide confidence intervals, the unit root null hypothesis cannot be rejected in these cases.  相似文献

Research summary : Prior scholarship has assumed that firm‐specific and general human capital can be analyzed separately. This article argues that, in some settings, this is not the case because prior firm‐specific human capital investments can be a market signal of an individual's willingness and ability to make such investments in the future. As such, the willingness and ability to make firm‐specific investments is a type of general human capital that links firm‐specific and general human capital in important ways. The article develops theory about these investments, market signals, and value appropriation. Then, the article examines implications for human resource management and several important questions in the field of strategic management, including theories of the firm and microfoundations of competitive advantage. Managerial summary : While managers don't often use the terms firm‐specific and general skills, they certainly recognize that investments employees make in their skill sets are more or less relevant to a specific firm. For instance, investing in specific relationships within a firm or learning a firm's proprietary software would be considered firm‐specific investments. While such skills may seem relevant only to the particular firm in which they were invested, these investments may also send valuable signals to competing firms that such employees are willing and able to make similar investments elsewhere. Hence, managers should be interested in determining if a potential hire has made prior firm‐specific investments to help them know whether that person might be likely to make such investments in his or her future place of employment.

This article discusses how the slowdown in the real estate market during the most recent economic and financial crisis has affected residential tourism destinations on the Spanish coast. The afore-mentioned crisis, which gave rise to a standstill in residential activity, coincided with the turbulences experienced in the competing destinations of Northern Africa, which brought about a record number of international tourist arrivals to Spain. The resulting situation enables us to explore the future scenario of all the Spanish destinations that, due to the depletion of available land, are reaching their maximum levels of urban growth. Examining the case of Calpe, a destination which is representative of the Spanish Mediterranean, the study analyses whether the foreseeable dynamics for the future are conceptualized in the favourable terms that characterize “sustainable development” or, on the contrary, exhibit negative implications which the classic economists refer to as the “steady state”.  相似文献

In 2015, the Brazilian economy was afflicted by a lethal combination of a falling level of activity and accelerating inflation. Expectations for 2016 are equally or even more adverse, since the effects of rising unemployment emerge only after a lag. The domestic debate has opposed analysts who believe the crisis is due exclusively to past policy mistakes to analysts who believe that all was well until the government decided to implement austerity policies in 2015. A closer examination of the evidence shows that in fact both reasons contributed to causing the crisis, but it also suggests that its depth has a more proximate cause in the political collapse of the federal government in 2015, which led Brazilian society to an impasse for which a solution is not yet in view.  相似文献

Summary This paper establishes an existence theorem of a non-trivial (positive capital stock) steady-state equilibrium in Diamond's (1965) overlapping-generations model with production by employing the steady-state consumption curve introduced in Ihori (1978). The assumptions on preferences and production technologies that ensure the existence of a nontrivial steadystate equilibrium are separated from each other, unlike in Galor and Ryder (1989). We also provide two simple examples which illustrate the importance of two conditions in the theorem.Detailed comments by Tomoichi Shinotsuka and the referees of the journal were quite helpful.

The empirical analyses of firm diversification decisions, both for new activities (new products) and markets (for example, new routes for airlines), have usually estimated a binary dependent variable model for each of the decisions the firm makes. To obtain consistent estimators, every relevant effect must be considered in the specification. As this will hardly happen, the presence of nonobserved firm effects (either because such data do not exist or because it is impossible to obtain them) must be econometrically treated, because it causes inconsistency in the estimations. In this paper we propose to use the estimators provided by the maximization of the conditional likelihood function in problems of this kind because they give consistent results even when unobserved firm effects are present. Finally, we apply this technique to an example of diversification among Spanish manufacturers. © 1997 John Wiley & Sons, Ltd.  相似文献

Consumers’ perception of, and satisfaction with, fruit quality is an important issue for both public policy and commercial reasons. However, because of information problems, consumers cannot easily choose fruits of a quality most likely to satisfy their preferences and health needs. The research reported here employed an experimental auction method to test perceptions of fruit quality by evaluating the willingness to pay (WTP) of consumers for five different varieties of soft citrus under three different information conditions: visual inspection of the fruit before peeling; visual inspection after peeling; and after consumption. Significant differences were found in valuations of the different varieties as consumers gained information. Conclusions are drawn about the value of the methodology and the results themselves, and implications are inferred for policy and for growers and traders. It is argued that product information should be oriented not just towards nutritional education but also towards increasing the pleasure of healthy eating.  相似文献

The calculus of VaR involves dealing with the confidence level, the time horizon and the true underlying conditional distribution function of asset returns. In this paper, we shall examine the effects of using a specific distribution function that fits well the low-tail data of the observed distribution of asset returns on the accuracy of VaR estimates. In our analysis, we consider some distributional forms characterized by capturing the excess kurtosis characteristic of stock return distributions and we compare their performance using some international stock indices.
