Acquisition of innovative firms is a widely observed phenomenon in high-tech industries. On the basis of distinct advantages of large and small firms, in this paper, we build a tournament model with possible acquisition activity of large firms to derive hypotheses on interdependencies between acquisition frequency and post-acquisition success rates. We find empirical support for our hypotheses that (1) acquisitions increase overall innovation output and (2) that the number of acquisitions is higher in industries with larger heterogeneity between established firms and young start-ups. However, our third hypothesis derived from the formal model that innovation success following from acquisitions varies across industries is only partially confirmed. 相似文献

Recent analysis on New Regionalism has, for Björn Hettne, raised important ontological questions over ‘what we study when we study regionalism’. The paper contributes to this debate by focusing on the shared beliefs, norms and rituals that hold a region together. Working between the New Regionalism literature and thinking on international regimes, this paper – to paraphrase Friedrich Kratochwil and John Ruggie – outlines the ‘inescapable inter-subjective quality’ of a region. This focus on inter-subjectivity seeks to improve on existing approaches that consider shared social structures as already fixed, and/or as autonomous constructs operating over and above regional actors. In order to appreciate how inter-subjective structures and regional agents interact with each other, the paper explores the social construction of Latin America. Specifically, it examines the politics of regionness – understood here in relation to identity, space and agents – to demonstrate how various regional actors operate within, and reconstruct, shared meaning. In so doing, it interrogates the practices that govern and continually produce the region. 相似文献

We use panel data for nine industries to evaluate research and development (R&D) investments in New Zealand over the past forty years. We estimate the impact of R&D stocks in a particular industry on output per person in that industry and on output per person in the rest of the economy. We examine both public and private R&D investments. Privately provided R&D has a statistically significant positive impact on own-industry output per person, suggesting it increases productivity. However, publicly provided R&D has no impact on own-industry output per person. There is also evidence that private R&D in certain industries positively affects output per person in the rest of the economy, i.e. it generates positive spillovers. There is no evidence of positive spillovers from publicly provided R&D. 相似文献

The ‘right to request’ policy encouraged and supported National Health Service (NHS) community health staff in England to ‘spin out’ services into independent social enterprises. This article considers the processes and outputs of the initiative and reflects on the likelihood of positive outcomes for patients being achieved. It highlights lessons for future programmes seeking to transfer services out of public ownership. 相似文献

Using the Mirrlees optimal income tax model under maximin, we derive fairly mild conditions for a decreasing marginal tax rate throughout the skill distribution with no bunching, a strictly concave tax function in income and a single-peaked average tax schedule. Assuming additive preferences and an isoelastic disutility of labor function, these tax profiles are implied by aggregate skills that are non-decreasing with the skill level. If preferences are quasilinear in leisure or in consumption, these tax profiles are also obtained under a large set of skill distributions. 相似文献

“The quiet life hypothesis” (QLH) by Hicks (1935) argues that, due to management’s subjective cost of reaching optimal profits, firms use their market power to allow inefficient allocation of resources. Increasing competitive pressure is therefore likely to force management to work harder to reach optimal profits. Another hypothesis, which also relates market power to efficiency is “the efficient structure hypothesis” (ESH) by Demsetz (1973). ESH argues that firms with superior efficiencies or technologies have lower costs and therefore higher profits. These firms are assumed to gain larger market shares which lead to higher concentration. Ignoring the efficiency levels of the firms in a market power model might cause both estimation and interpretation problems. Unfortunately, the literature on market power measurement largely ignores this relationship. In the context of a dynamic setting, we estimate the market power of US airlines in two city-pairs by both allowing inefficiencies of the firms and not allowing inefficiencies of the firms. Using industry level cost data, we estimate the cost function parameters and time-varying efficiencies. An instrumental variables version of the square root Kalman filter is used to estimate time-varying conduct parameters. 相似文献

The impacts of tourism have been given much consideration by scholars attempting to investigate the attitudes of the host population toward tourism. Such studies have been carried out in rural, coastal as well as in urban areas. However, most studies on urban tourism impacts have been conducted in the context of the developed world, whereas very little research has been carried out in the urban environment of Small Island Developing States. Using a sample size of 230 residents, this study contributes to the limited literature on urban tourism in islands by examining the residents' attitudes toward tourism in Port Louis, the capital city of the island of Mauritius. Findings suggest that while the positive impacts of tourism are well recognized by the residents, the latter are also concerned with some negative influence of tourism in Port Louis. Residents were found not to be homogeneous in their perceptions toward tourism. Employment in tourism was found to be an antecedent of attitudes. Gender and age were also found to be discriminators toward some tourism impact. Findings also revealed that residents were supportive of cultural tourism development. Implications for the management of the small island urban tourism are also discussed. 相似文献

This study addresses current gaps in the empirical literature regarding the effect of diplomatic representation on trade using a panel data set for 100 countries with 5‐year interval data from 1985 to 2005 and four‐digit level industry data. The results indicate that the effect of diplomatic representation on exports in differentiated goods is positive and significant and larger than on exports in homogeneous goods on average, but not statistically different from it. Furthermore, diplomatic representation only increases trade along the extensive margin and not along the intensive margin. The results indicate that diplomatic representation is effective in performing its function as a network search intermediary and that it is a useful policy tool to alleviate market failure. 相似文献

A moneyness‐based propensity to sell (MPS) measure, at the aggregate level, determines the propensity of option holders to exercise their winning relative to losing positions. Using data on individual stock and S&P 500 Index options, we find that the MPS measure has significant predictive power over the cross section of delta‐hedged option returns. We test the disposition effect in the options market based on a long–short strategy that exploits price distortions induced by the disposition bias. More pronounced evidence of the disposition bias is found for individual at‐the‐money call options than put options where the significance of abnormal returns remains robust across different subsamples even after we control for the portfolio option greeks and market‐based risk factors. The profitability of the long–short strategy is related to limit‐to‐arbitrage proxies suggesting that behavioral explanations help explain the positive relation between the MPS measure and delta‐hedged option returns. 相似文献
