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

An experimental auction and the eye-tracking technology are used to detect the relationship between consumers’ understanding of the nutrition information and their willingness to pay for food items. Additional attention is given to health-conscious individuals. Salad mix and apple juice are selected for the experiment. A Tobit model is used for the analysis. The results show that nutrition information has some effect on consumers’ purchasing decision. Shoppers are willing to pay less for fat and mineral information, but more for ingredient, protein, sodium, and carbohydrate information of salad mix. As for apple juice, shoppers care only for energy and other nutrient information, as well as the health claim “vitamin C naturally high.” Further, health-conscious individuals are more responsive to the nutrition claims, such as “high in fiber” (salad mix) and “vitamin C naturally high” (orange juice). A possible limitation of the conclusion exists due to the small sample size.  相似文献

The goal of this paper is to analyze the impact of annual earnings announcements on the market through the order flow data in addition to the usual transaction data. In this respect, examining order flow data can potentially reveal valuable information that is not available from transaction data. In fact, the data allow us to test hypotheses about asymmetric information and investor behavior and to test if the behavior varies with investor sophistication. In addition, the paper tries to identify the determinants of the impact on a firm's value using assumptions about investor behavior.  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

The effect of within-group heterogeneity on the survival of social groups is theoretically ambiguous. A greater diversity of ideas, experience, and networks can have a positive effect on members’ benefits from group membership, but diversity also creates a potential for conflict. This paper analyzes the relation between heterogeneity and exit of microcredit groups, using data from Angola. The results suggest that the form of group heterogeneity matters. Fragmentation in terms of social identities, or more specifically religious-linguistic fractionalization, is associated with a greater probability of group exit. Within-group economic inequality, however, is associated with a decrease in the probability of exit, but at a diminishing rate.  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

This paper describes the degree of trade integration inside the European Union (EU) after the fifth enlargement in 2004. To achieve this goal, we build a database of information on trade flows between the new EU countries (EU‐10) and 180 commercial partners in six different sectors from 1999 to 2011. Using the standard gravity model and estimating a difference‐in‐differences specification, we analyze how joining the EU affected the intensity and direction of the EU‐10's trade flows. Our results show that though trade exchanges between the EU‐10 and EU‐15 intensified after 2004, the impact of integration was much more significant to the EU‐10 group.  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
