A quadratic version of the first-difference Okun’s Law model was estimated for Spain (1995.Q1-2012.Q2). An accelerationist version of Okun’s Law was obtained, which allowed us to calculate variable Okun coefficients as well as critical points in the relationship between construction sector growth and the variation in overall unemployment. The optimal economic growth rate was determined to be 7.38 %. By applying principal components, it is demonstrated that this sector led the economic process after 1995. 相似文献

We use a newly assembled sample of 1,528 regions from 83 countries to compare the speed of per capita income convergence within and across countries. Regional growth is shaped by similar factors as national growth, such as geography and human capital. Regional convergence rate is about 2 % per year, comparable to that between countries. Regional convergence is faster in richer countries, and countries with better capital markets. A calibration of a neoclassical growth model suggests that significant barriers to factor mobility within countries are needed to account for the evidence. 相似文献

Entrepreneurial activity varies significantly across countries and over time. The economic and institutional context is a determining factor that can drive and lend shape to entrepreneurial activity. The search for a deeper understanding of the role of this factor constitutes a promising and important research stream. A thorough review of the specialist literature identifies groups of countries with similar economic and institutional environments. Subsequent analysis highlights differences in entrepreneurial activity and innovation outcomes between these homogeneous groups. Results indicate significant differences, not only in entrepreneurial activity, but also in the type of entrepreneurship and innovation results. These findings mark a relevant step forward in the identification of different environment types, and the effects of environment on entrepreneurial activity and innovation results. 相似文献

Recent literature for developed economies has shown that output gap estimates go through important revisions over time, impairing their reliability in real time. We organize a real-time data set for Brazil’s GDP and assess the revisions of the output gap estimated by four different methods. Similar to the findings of studies for developed economies, the output gap revisions in Brazil are substantial in all methods, with frequent changes in the output gap sign. In general, both the GDP data revision and the effect of adding new observations to the sample are relevant sources of output gap revisions. However, differently from those studies, we cannot assert that the latter source is preponderant. 相似文献

We construct an industry-equilibrium model in which it is costly for consumers who have previously purchased from one firm to switch to competitors. This gives firms a certain degree of market power over their established customers. The equilibria we identify under these conditions have the following properties: (1) there is a nontrivial size distribution of firms, although firms are intrinsically identical, (2) larger firms make higher profits, (3) larger firms spend more on R&D, (4) larger firms charge (on average) lower prices, and (5) profits are positively correlated over time. These properties match empirical regularities concerning the manufacturing and retail sectors in the U.S. economy. 相似文献

Studies of ‘futures’ have hitherto focused on those that are predictable and ‘tame’, and on those that are unpredictable and ‘wild’. Here we consider a new class, the ‘feral’; which are expectations that things might be made worse by risk-based actions. The type case is the nuclear accident at Three Mile Island, where operatives assumed that what was unfolding was of a sort described in their manual, and discovered too late that responses based on that assumption were making the situation worse. In this paper we review the idea of ‘feral’ and how it applies to futures, and discuss the different modes of engagement (or non-engagement) with feral futures. To make feral futures manageable, we suggest two ideas from other spheres of activity. Zen is a practice and philosophy which enables us to drop our preconceptions and thereby to respond to emerging, unprecedented situations. Aesthetics articulates a particular way to sense and appreciate realities intuitively, again enabling a direct response. The combination of Zen and aesthetics with scenario practice in the tradition of Pierre Wack provides a promising mode of response to emerging feral futures. 相似文献

In 1992 a blue‐ribbon group of US economists led by Michael Porter concluded that the US stock market‐based corporate model was misallocating resources and jeopardising US competitiveness. The faster growth of US economy since then and the supposed US lead in the spread of information technology has brought new legitimacy to the stock market and the corporate model, which is being hailed as the universal standard. Two main conclusions of the analysis presented here are: (a) there is no warrant for revising the blue‐ribbon group’s conclusion; and (b) even US corporations let alone developing country ones would be better off not having stock market valuation as a corporate goal. 相似文献

This paper shows that a multiproduct firm may find it optimal not to delegate the sales of all products and therefore to employ different distribution channels for different products. It faces the following trade-off: There is a strategic effect associated with delegation, but if both products' sales are delegated, intrafirm competition is not internalized. By delegating the sales of just one of the products while selling the other product directly—partial delegation—the multiproduct manufacturer strikes just the right compromise: The externalities between its owns products are internalized partially while a strategic advantage is achieved against its rival single-product manufacturer. Partial delegation also holds if both products are sold by a common retailer; it dominates full delegation when both manufacturers are multiproduct firms . 相似文献

The article considers the social services supply in the Spanish area of Valencia. The objective is double. First the authors analyse what describes the partnership between public sector and NPO in this area, by using a systemic conception of the social services sector where three main functions can be identified (financing, production and distribution, and regulation). Secondly they search for theoretical arguments explaining this partnership principle. This second section is mainly based on the NPO approach. 相似文献

This paper examines the wealth position of blacks relative to whites, on the basis of data in the Survey of Economic Opportunity. The analysis indicates that at the same levels of both income and wealth blacks consistently invest more in consumer durables, especially housing, than do whites. The paper then explores possible explanations for this finding, suggesting that these investment differences are not solely due to the income and wealth position of blacks, but may be due to a smaller set of investment opportunities institutionally fostered by discriminatory forces. 相似文献
