Gastronomy has been established as one of the key elements for the promotion and consolidation of tourist destinations. The current aim is to contribute to the scientific literature in the field of the relationship between gastronomy and tourism in Latin America from the experience affirmed by North American tourists in the city of Cuenca (Ecuador). The methodology is based on a questionnaire presented to North American travelers during their visit to the city of Cuenca. The results show the existence of different segments of tourists in relation to their attitude toward the local gastronomy. Three segments are identified, and depending on their belonging to a certain segment, the tourists have different motivations with respect to gastronomy. Finally, the results permit concluding that the levels of satisfaction of the tourists differ depending on their attitude toward gastronomy, identified by the three segments.  相似文献

In this article, we extend the traditional GARCH(1,1) model by including a functional trend term in the conditional volatility of a time series. We derive the main properties of the model and apply it to all agricultural commodities in the Mexican CPI basket, as well as to the international prices of maize, wheat, swine, poultry, and beef products for three different time periods that implied changes in price regulations and behavior: before the North American Free Trade Agreement (NAFTA; 1987–1993), post‐NAFTA (1994–2005), and commodity supercycle (2006–2014). The proposed model seems to adequately fit the volatility process and, according to heteroscedasticity tests, also outperforms the ARCH(1) and GARCH(1,1) models, some of the most popular approaches used in the literature to analyze price volatility. Our results show that, consistent with anecdotal evidence, price volatility trends increased from the period 1987–1993 to 1994–2005. From 1994–2005 to 2006–2014, trends decreased but the persistence of volatility increased for most products, especially for international commodities. In addition, we identify some agricultural products such as avocado, beans, and chicken that, due to their increasing price volatility trends in the 2006–2014 period, may present a risk for food inflation in the short run.  相似文献

Previous research has shown that changes in the composition of tax revenue affect long-run growth. However, little is yet known about whether the way tax revenue is raised matters for growth. This paper examines whether, in the context of OECD countries, a revenue-neutral increase in the value-added tax (VAT), offset by a fall in income taxes, may have different effects on long-run growth depending on how the VAT is raised. We show that a revenue-neutral rise in the VAT promotes growth when it is raised through a rise in C-efficiency, while it does not when it is raised through a rise in the standard VAT rate, the rate applied to the largest portion of taxed consumption. C-efficiency measures the departure of the VAT from a perfectly enforced tax levied at a single rate on all consumption, which in advanced economies is largely due to the VAT that is not levied because of exemptions and reduced rates. Thus, our results suggest that an increase in C-efficiency, possibly reflecting the broadening of the VAT base through fewer exemptions and a more uniform rate structure with fewer reduced rates, promotes growth more than a rise in the standard rate.

Why is high-growth entrepreneurship scarce in developing countries? Does this scarcity reflect firm capabilities constraints? We explore these questions using as a laboratory an accelerator in Colombia that selects participants using scores from randomly assigned judges and offers them training, advice, and visibility but no cash. Exploiting exogenous differences in judges’ scoring generosity, we show that alleviating constraints to firm capabilities unlocks innovative entrepreneurs’ potential but does not transform subpar ideas into high-growth firms. The results demonstrate that some high-potential entrepreneurs in developing economies face firm capabilities constraints and accelerators can help identify these entrepreneurs and boost their growth.  相似文献

Drawing on a large database from the register of inhabitants of Madrid, this article confirms that the literacy levels of internal migrants moving to the Spanish capital city in the late nineteenth and early twentieth century were higher than that of those who remained in their provinces of origin. This article also explores the different factors influencing the nature and intensity of the selection process. The empirical exercise stresses that the stock of previous migration was a fundamental factor in allowing less literate individuals to join the migration process as well. Interestingly, distance to Madrid hardly affected the profile of male migrants, but it was a strong influence on female migration, although its importance diminished over time. Lastly, the results presented here show that other internal destinations were attracting different types of migrants, often resulting in negative self‐selection.  相似文献

This paper is the first that quantifies the impact of single windows (SWs) on international trade globally. SWs function as a single point of entry and exit of the goods traded internationally and are therefore intended to facilitate trade. Using a structural gravity model for a panel of 176 countries from 1995 to 2017, we apply a log–log and a Poisson pseudo-maximum-likelihood estimator (PPML) with multidimensional fixed effects to evaluate the extent to which export and import flows vary depending on whether or not countries have operational SWs. The main results from the linearised gravity model suggest that total trade between two countries with functioning SWs increases by about 37%, of which 23 corresponds to exports and 14 to imports. The result from the PPML estimation also indicates a positive and significant effect, which is however much smaller in magnitude.  相似文献

Correct estimation of the Outstanding Claims Reserve, an item that includes Incurred But Not Reported Claims (IBNR) as well as Incurred But Not Enough Reserved Claims (IBNER), is one of the most important issues currently facing actuarial science, due to its effect on the technical and financial stability of insurance companies. The purpose of this paper is to calculate the reserve in a decision-making environment, so that estimates can be made according to accurately defined and previously established rational criteria. Specifically, the estimating process enables a company’s particular situation to be taken into account, by incorporating its approach to the consequences arising from estimation errors into the model. The proposed calculation method gives rise to optimum link ratio estimators that can also be interpreted from a Bayesian perspective, with the advantages associated to such methodology.  相似文献

This article examines the determinants of local tax rates. For the two main local taxes in Spain—the property tax and the motor vehicle tax—we test the existence of tax mimicking, yardstick competition, and political trends in a sample of 2,713 municipalities. Using various spatial models, the results support the hypothesis of tax mimicking, with coefficients above 0.40. We also show the relevance of political variables such as the ideology of incumbents and political fragmentation. The fact that incumbents with weaker political support exhibit stronger mimicking behavior is interpreted as evidence in favor of yardstick competition. Finally, we find that incumbents mimic neighboring municipalities ruled by the same political party, confirming the political trends hypothesis. (JEL C31, H71, H77)  相似文献

Participatory democracy is a process of collective decision making that combines elements from both direct and representative democracy: Citizens have the power to decide on policy proposals and politicians assume the role of policy implementation. The aim of this paper is to understand how participatory democracy operates, and to study its implications over the behavior of citizens and politicians and over the final policy outcomes. To this end, we explore a formal model inspired by the experience of Participatory Budgeting implemented in the Brazilian city of Porto Alegre, that builds on the model of meetings with costly participation by Osborne et al. [2000. Meetings with costly participation. American Economic Review 90, 927-943].  相似文献
