This article aims to evaluate the service quality experienced at academic conferences held at the Universidad Técnica Particular de Loja in Ecuador. Our approach is based on fuzzy logic and ideal solutions to calculate a global attendee satisfaction index for specific market segments: Gender, nationality, and age. Current literature on the service quality experienced by conference attendees is still scarce. Our results show that the analyzed segments experience varying levels of satisfaction, and that the more influential attributes to each of them are also different. Our results can be applied to improve the competitiveness of Loja and that of Universidad Técnica Particular de Loja. 相似文献

The impacts of international tourism demand on economic growth of small economies dependent on tourism 总被引:1,自引:0,他引:1
This paper studies the impacts on economic growth of a small tourism-driven economy caused by an increase in the growth rate of international tourism demand. We present a formal model and empirical evidence. The ingredients of the dynamic model are a large population of intertemporally optimizing agents and an AK technology representing tourism production. The model shows that an increase in the growth of tourism demand leads to transitional dynamics with gradually increasing economic growth and increasing terms of trade. In our empirical application, an econometric methodology is applied to annual data of Antigua and Barbuda from 1970 to 2008. We perform a cointegration analysis to look for the existence of a long-run relationship among variables of economic growth, international tourism earnings and the real exchange rate. The exercise confirms the theoretical findings. 相似文献

The univariate statistical properties of agricultural price series need to be examined as a first step in the analysis of price transmission mechanisms. However, in the case of weekly price series, increasingly available, the testing procedures usually applied in this step are not suitable to deal with evolving seasonal effects. In this study, a method of testing for seasonal unit roots in weekly series of agricultural prices is described. When the deterministic seasonal component does not remain constant over time, the restricted evolving spline model (RESM) is shown to be a useful parametric formulation to capture the deterministic seasonal pattern. Therefore, the RESM model should be included as a deterministic component in auxiliary regression for unit root tests at seasonal frequencies. This proposal is applied to three weekly series of Canary Islands banana prices. From the standard seasonal unit root tests, the null hypothesis is failed to be rejected at the 5% or 10% significance level at some seasonal frequencies for each one of the series. Once critical values are obtained by simulation exercises when the RESM model is included, the hypotheses of unit root are rejected at each one of the seasonal frequencies for all of the three series. 相似文献

This paper demonstrates a time-series production technique to quantify the deer harvest and deer hunting benefits of controlled burns or prescribed fire. The time series regression model showed a statistically significant and positive effect of prescribed fire on deer harvest. The net economic value of the resulting additional deer hunting benefit was estimated using the Contingent Valuation Method at $ 98 per additional deer harvested. The initial deer hunting benefits of an additional 1,000 acres of prescribed burning are between $ 2,674 and $ 3,128 or $ 2-3 per acre. The costs of prescribed burning greatly exceed these benefits, suggesting that deer hunting benefits represent only a small part of the multiple use benefits of prescribed fire. 相似文献

Price transmission,asymmetric adjustment and threshold effects in the cotton supply chain: a case study for Vidarbha,India 下载免费PDF全文
This study examines price transmission asymmetries in Vidarbha's (India) cotton supply chain from 2002 to 2012. The analysis takes account of thresholds in price adjustments toward their long‐run equilibrium. The first stage considers the price dynamics between international and Indian domestic cotton prices. The second stage considers price transmission from domestic to farm gate cotton prices in Vidarbha. Results from the first stage indicate that Indian and international cotton markets are well‐integrated. In contrast, the second stage reveals significant threshold‐type nonlinearities as well as asymmetries in price transmission between domestic and farm gate prices. The short‐run dynamics suggest that the pass‐through from domestic to farm gate prices is larger when domestic prices decrease than when they increase. Moreover, back of the envelope calculations suggest that the loss in revenue for a typical farmer from a decrease in domestic price is larger than the gains from an increase in domestic price of the same magnitude. The implication is that traders benefit from price fluctuations at the expense of farmers. Evidence from fieldwork in Vidarbha suggest that asymmetries revealed in this analysis may be linked to trader's market power and inadequate market information among farmers. 相似文献

Emilio Galdeano-Gómez 《Environmental and Resource Economics》2008,40(1):73-89
The aim of this paper is to analyse the relationship between environmental and economic performance from the resource-based
theory within firms of the fresh fruit and vegetables sector. This study considers that the adoption of environment-friendly
practices has a greater influence on firms’ opportunities and abilities in the agricultural sector than in manufacturing sectors
and leads to closer links between performance variables. The reference for this empirical analysis is a panel data of horticultural
farming-marketing firms in Spain. The voluntary environmental programmes and the heterogeneity of their application lead us
to regard acquiring a competitive advantage as a relevant driver to improve environmental performance in this sector. A simultaneous
equations model is suggested reflecting the differential environmental effect and the assumption of endogeneity among variables.
The results show a positive impact of environmental differentiation on profitability and market share, also suggesting that
the perception of this positive experience implies greater environmental performance.

This paper investigates the relationship between patents and research and development expenditures using new longitudinal
patent data at the firm level for the U.S. manufacturing sector from 1982 to 1992. The paper also develops a new class of
count panel data models based on series expansion of the distribution of individual effects. Estimation results from various
distributed lag and dynamic multiplicative panel count data models show that the contemporaneous relationship between patenting
and R&D expenditures continues to be strong, accounting for over 60% of the total R&D elasticity. The lag effects are higher
than have previously been found for the 1970s data.
We would like to thank Chris Bollinger, Bronwyn Hall and Paula Stephan for useful comments on the previous version of the
paper. Earlier versions were presented at the 11th International Conference on Panel Data, Texas A&M University, the Midwest

We document the patterns of market-wide and firm-specific volatility in the Portuguese stock market over the 1991–2005 period
and test several explanations for the behavior of firm-level idiosyncratic volatility. Unlike previous studies we find no
evidence of a statistically significant rise in firm-specific volatility. On the contrary, the ratio of firm-specific risk
to total risk slightly decreases. We show that this result stems from new listings of large privatized companies that display
lower firm-specific risk. Our findings are consistent with the idea that changes in idiosyncratic volatility are related to
changes in the composition of the market.

We introduce asymmetric information about consumers’ transportation costs (i.e., the degree of product differentiation) in the model of Hotelling. When transportation costs are high, both firms have lower profits with asymmetric information than with perfect information. Contrarily, if transportation costs are low, both firms may prefer the asymmetric information scenario (the informed firm always prefers the informational advantage, while the uninformed firm may or may not prefer to remain uninformed). Information exchange is ex‐ante advantageous for both firms, but ex‐post damaging if transportation costs turn out to be low. If the information is unverifiable, the informed firm does not represent a reliable source of information, since it always prefers to announce that transportation costs are high and there is no contract that induces truthful revelation. 相似文献

Informality is a defining characteristic of labour markets in developing and transition countries. This paper analyzes patterns of mobility across different forms of formal and informal employment in Russia. Using the Russian Longitudinal Monitoring Survey household panel we estimate a dynamic multinomial logit model with individual heterogeneity and correct for the initial conditions problem. Simulations show that structural state dependence is weak and that transition rates from informal to formal employment are not lower than from non-employment. These results lend support to the integrated view of the labour market. 相似文献
