This paper analyzes how the use of endogenous direct advertising affects the functioning of a horizontally-differentiated market. We formulate a two-stage game of pricing and informative advertising in which two firms, first, compete with mass advertising and, later, build a database using their historical sales records and compete by directly targeting the ads on their potential customers. We show that, compared to the case where firms only use mass advertising, direct advertising yields higher advertising efforts and an intertemporal reallocation of both market power and profits from the first to the second period. We also find that targeting increases the overall firms’ profit and the level of social welfare, but the impact on the average intertemporal price and consumer surplus is ambiguous. Finally, when reaching the potential market with mass advertising is sufficiently expensive, the use of direct advertising leads firms to provide the socially optimal level of advertising whereas, if mass advertising is cheap, firms tend to launch too little advertising in the first period and too much in the second.  相似文献

Is the ongoing economic slowdown in industrialized countries likely to impact Latin American growth negatively in the medium- to long-run? This paper considers various transmission channels that work through trade in goods and services, and finds econometric evidence suggesting that shrinking global imbalances may create problems for Latin America. Specifically, using panel data analysis, we find that the trade balance as a proportion of GDP is positively associated with Latin American economic growth over the period 1953–2009. We then develop a simple dynamic model to help explain our main finding through investment and saving behaviour.  相似文献

This paper studies the effect of government-backed partial credit guarantees on firms’ performance in Colombia. These guarantees are automatically granted by the National Guarantee Fund (NGF) to firms without enough collateral to lift their credit constraints. We put together a panel of firms covering the period 1997–2007 that allows us to control for observed and unobserved firm characteristics potentially affecting both the selection of firms into the program and firms’ performance. We find that firms that gain access to credit backed by the NGF were able to grow in terms of both output and employment. However, we do not find any effect on productivity, wages, or investment.  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

The chinampas (raised beds) of Xochimilco, Mexico City, are highly productive, traditional wetland agricultural systems, which were able to feed most of the population in pre-hispanic times. There is a strong trend to substitute chinampas with plastic greenhouses for flower production, which creates negative impacts in the landscape, environment and culture. This study compares the environmental and socio-economic sustainability of chinampas and greenhouses, at both the farm and regional levels, using the MESMIS framework. Even though the results show that greenhouses are more profitable, the contribution of chinampas to ecosystem services cannot be substituted by greenhouses, as tree cover is lost, canals are filled and food is not provided. Greenhouses had a higher diversity, but also a higher agrochemical use and are heavily dependent on external inputs and subsidies. Chinampas have shifted from staple crops to commercial horticulture in order to remain a technically viable and economically feasible option for local farmers. However, compensation mechanisms for the provision of ecosystem services are urgently needed if this ancient system is to be maintained. The framework allowed the integration of indicators at both farm and regional scales, combining on-farm surveys with GIS techniques, which could assist in ecosystem service valuation.  相似文献

Policy makers have traditionally considered the macroeconomic relations and the variables that can affect the economic objectives that they pursue, such as prices, employment, balance of payments, and economic growth. Recently, microeconomic behavior has also been considered. To complete the analysis, it is necessary to include those variables that define the firm's evolution and activities, and cash flow could be this kind of variable to be included in the analysis. The main objective of this paper is to show the relationship between cash flow and one of the final economic policy targets, economic growth. This paper considers the relationship between cash flow and applied economics, then develops the effects of cash flow on economic growth.  相似文献

ϕ-divergence statistics quantify the divergence between a joint probability measure and the product of its marginal probabilities on the basis of contingency tables. Asymptotic properties of these statistics are investigated either considering random sampling or stratified random sampling with proportional allocation and independence among strata. To finish same tests of hypotheses of independence are presented. The research in this paper was supported in part by DGICYT Grants No. PS91-0387 and No. PB91-0155.

This paper analyses whether the hotel classification system is a good indicator of hotel quality, where quality is defined to be satisfying the expectations and needs of the client. We conducted our research in Spain, where a five-category system using stars is employed. To be exact, the hotel sector of one autonomous community (Cantabria, located in northern Spain) was studied, given that it is these autonomous regions that have exclusive authority to regulate and promote tourism. The results of the study confirm that even though significant quality differences are seen between the different categories, the ranking by quality does not correspond to that by categories. This supports the idea that quality is associated with the delivery of a service according to client expectations, more than it is with establishment category.  相似文献

The crisis of the new economy might have cast doubt on the usefulness of the Internet for business activities. However, it is unquestionable that the possibilities offered by Internet-based technologies in terms of information processing, transfer and collection enable the firm to improve market knowledge and the relationship with clients and suppliers. This work explores, theoretically and empirically, the possibilities offered by the Internet to facilitate the internationalization process of Small and Medium Enterprises (SMEs) as well as to improve the relationship with other firms within the same value chain. Using a wide representative sample of Spanish SMEs, the empirical analysis confirms the benefits of the Internet in both cases.  相似文献
