Estimating Krugman’s Economic Geography Model for the Spanish Regions   总被引:1,自引:0,他引:1  
This paper estimates Krugman’s (J Polit Econ 99:413–499, 1991) economic geography model using data from the Spanish NUTS 3 regions. The econometric formalization endogenously determines wages in a region as a function of income and wages in other regions. The specification adopted also allows us to study the relation between the agglomeration of economic activity, increasing returns and market access. The first result obtained is that the Spanish economy exhibits a spatial wage structure: wages in a region are positively determined by income and wages in neighboring regions. In second place it is found support for the structural relations of the underlying theoretical model, indicating the importance of scale economies and transport costs in shaping the Spanish economic geography.  相似文献

Managers need guidance on how to cope with turbulent environments in order to improve corporate performance. Research on environmental turbulence has suggested that firms adopt a less centralized, more organic structure in dynamic, uncertain environments. Little work has been done specifically, however, on how environmental turbulence affects strategy planning for new product development (NPD). In this article, we specify a baseline model with firm innovativeness, market orientation and top management risk taking as antecedents to NPD speed and corporate strategic planning; these in turn are modeled as antecedents to NPD program (not project) performance. Two conceptualizations of the role of environmental turbulence are examined: (1) that market turbulence and technological turbulence are additional direct antecedents to NPD program performance; and (2) that the baseline model is moderated by turbulence (that is, that the strengths of the paths differ depending on levels of turbulence). A cross-sectional survey methodology including four diverse industries [automotive, electronics, publishing, and manufacturing/research and development (R&D) laboratories] was used to test the hypotheses. The latter conceptualization is supported. In particular, the paths from innovativeness to strategic planning and from risk taking to NPD speed are significantly greater in highly turbulent environments. A set of managerial recommendations and implications are provided. First, managers must recognize the possible improvements in new product performance by actively including NPD personnel in corporate strategic planning and also by involving corporate planners in NPD activities. Second, managers also should recognize that turbulent environments heighten the need to make risky investments, and sometimes, risky decisions; risk-taking decisions ought to be encouraged in such environments.  相似文献

We consider an industry composed of a multiproduct corporation that adopts corporate social responsibility (CSR) as a strategic managerial delegation and examine the profit-incentive to form a cooperative group. We find that competition is an equilibrium for any degree of substitutability and yields the highest CSR, which is increasing in the degree of substitutability. We also show that full cooperation is an equilibrium for lower substitutability but induces no CSR, whereas partial cooperation with one uniplant firm is an equilibrium for higher substitutability but yields lower CSR than that under competition. Therefore, cooperation might reduce strategic CSR activities, whereas competition will encourage higher CSR but yield lower industry profits.  相似文献

Several studies published in the last few decades have demonstrated a low price‐elasticity for residential water use. In particular, it has been shown that there is a quantity of water demanded that remains constant regardless of prices and other economic factors. In this research, we characterise residential water demand based on a Stone‐Geary utility function. This specification is not only theory‐compatible but can also explicitly model a minimum level of consumption not dependent on prices or income. This is described as minimum threshold or nondiscretionary water use. Additionally, the Stone‐Geary framework is used to model the subsistence level of water consumption that is dependent on the temporal evolution of consumer habits and stock of physical capital. The main aim of this study is to analyse the impact of water‐saving habits and water‐efficient technologies on residential water demand, while additionally focusing attention on nondiscretionary uses. This is informed by an empirical application using data from a survey conducted among residents of Brisbane City Council, Australia. The results will be especially useful in the design of water tariffs and other water‐saving policies.  相似文献

Three studies showed that the way that options are presented in a choice set—as combinations of intersecting attributes or in a more sequential “a la carte” choice format—affects the degree to which consumers adhere to their goals in the consumption setting. Specifically, using the context of food consumption and healthy eating, results showed that consumers were more likely to make double indulgent choices, the choice of both an indulgent entrée and an indulgent side item, when choosing from a menu consisting of predetermined “combination meals” than when selecting among the same entrée and side options in an a la carte fashion. Studies 2 and 3 implicated a goal distraction mechanism in driving the effect; the combination format, with its cross‐cutting of product choices into various combinations, reduces the salience of goal‐related constructs on implicit measures. In showing that different product presentation formats can affect the degree to which consumers make goal‐consistent choices, the current work adds to work on the effects of environmental influences on goal progress and goal achievement. Implications for encouraging goal‐consistent behavior in the context of healthy eating as well as other important consumer goal contexts are discussed.  相似文献

This paper explores the degree of interdisciplinarity of evolutionary approaches to the study of human behavior, and the implications that any such interdisciplinarity may have for the future of evolutionary psychology (EP) as a field of scholarship. To gauge the extent of interdisciplinarity of EP, the departmental affiliation of first-authors from 1000 journal articles evenly distributed across ten leading peer-reviewed psychology journals was assessed. Findings show that journals that are evolutionary-based have more first-authors from outside of psychology, and also include a wider variety of represented disciplines. These findings are discussed in terms of their influence on the future of EP, as a model for interdisciplinary research. EP's future will be successful if it continues to promote interdisciplinarity as well as recognize the epistemological worth of multiple evolutionary paradigms and frameworks. Evolutionary principles have been successfully applied to a broad range of topics, suggesting there is great utility in evolution serving as a common language for interdisciplinary pursuits within the behavioral and social sciences. As such, academic programs such as Evolutionary Studies (EvoS) programs, whose presence continues to increase across academic institutions worldwide, epitomize the future of successful interdisciplinary scholarly training.  相似文献

Estimating the cost of liquidity in agricultural futures markets is challenging because bid‐ask spreads are usually not observed. Based on an ability to reflect simulated data from Roll's spread model, we assess the effectiveness of conventional and Bayesian bid‐ask spread estimators under different market conditions. Conventional serial covariance and absolute price change spread estimators appear to be biased. Hasbrouck's Bayesian estimator generates small costs of liquidity whose values depend on the correlation and noise in the data. The absolute value Bayesian estimator is precise and works well under conditions of high levels of noise and correlation usually found in agricultural futures markets. Using data from live cattle (LC) and lean hog (LH) contracts, we find similar patterns of performance that produce economically meaningful cost of liquidity differences.  相似文献
