Agent-based models (ABMs) are becoming more relevant in social simulation due to the potential to model complex phenomena that emerge from individual interactions. In tourism research, complexity is a subject of growing interest and researchers start to analyse the tourism system as a complex phenomenon. However, there is little application of ABMs as a tool to explore and predict tourism patterns. The purpose of the paper is to develop an ABM that increases knowledge in tourism research by (i) considering the complexity of tourism phenomenon, (ii) providing tools to explore the complex relations between system components and (iii) giving insights on the functioning of the system and the tourist decision-making process. A theoretical ABM is developed to improve knowledge on tourist decision-making in the selection of a destination to vacation. Tourists’ behaviour, such as individual motivation, and social network influence in the vacation decision-making process are hereby discussed.  相似文献

This paper examines Portuguese firms’ survival over the business cycle and investigates whether the effect of firm size varies across the phases of the cycle and with the type of shock associated with periods of economic contraction. Our results show that smaller firms are more likely to shut down than larger firms. Within each size band, however, we found that during the two crises examined, micro firms experienced hazards of closing (relative to large firms) at least similar to those observed in the pre-crisis period, while medium-sized firms were found to have been more vulnerable during the financial crisis period but showed more resilience during the sovereign debt crisis. The results suggest that during the sovereign debt crisis, firms faced a higher probability of closing than they did during the financial crisis.  相似文献

Brand relationships through brand reputation and brand tribalism   总被引:2,自引:0,他引:2  
The academic research on branding of consumer products and services is increasingly considering the degree of connectedness between consumers and brands as a key issue of investigation. The literature in this area investigates the nature and the strength of the relationship that consumers develop with brands, as well as the trend of joining brand tribes or brand communities in order to demonstrate and share with others their feelings towards and preference to brands. However, the impact of the overall perceptions of the brands in the form of its reputation and brand tribalism on brand relationships is so far unexplored in the existing literature. Using data collected from 912 respondents, this paper explores the importance of the long term brand reputation and brand tribalism on the strength of brand relationships. The findings suggest that brand tribalism is a better predictor of the strength of brand relationships than the long term brand reputation itself.  相似文献

This paper empirically assesses the effectiveness of the Bank of Canada's term Purchase and Resale Agreement (PRA) facility in reducing funding pressures, as measured by the CDOR-OIS spread. It examines the behaviour of this spread around both term PRA announcement dates and term PRA operation dates, using an event-study methodology to control for developments in other money markets as well as proxies for Canadian banking sector credit risk. Overall, there is robust evidence that the term PRA announcements reduced bank funding costs at both 1-month and 3-month terms, whereas we find no evidence of an impact from term PRA operations.  相似文献

This paper examines the effects of Open Skies agreements on service levels in transatlantic aviation markets. Our route analysis reveals that Open Skies agreements between European countries and the US have resulted in both increases and decreases in service levels. Of the 22 European countries with US Open Skies agreements in place by 2007, only seven demonstrated increases in service levels while six showed reductions. Five countries saw no significant change and the remaining four have yet to receive direct transatlantic service, suggesting that liberalization alone does not lead to service level increases.  相似文献

Food price inflation in Brazil in the 12 months to June 2008 was 18%, whereas overall inflation was 7%. Using spatially disaggregated monthly data on consumer prices and two different household surveys, we estimate the welfare consequences of these food price increases, and their distribution across households. Because Brazil is a large food producer, with a predominantly wage‐earning agricultural labour force, our estimates include general equilibrium effects on market and transfer incomes, as well as the standard estimates of changes in consumer surplus. Although the expenditure (or consumer surplus) effects were large, negative and markedly regressive everywhere, estimates of the market‐income effect were positive and progressive, particularly in rural areas. Because of this effect on the rural poor, and of the partial protection afforded by increases in two large social assistance benefits, the overall impact of higher food prices in Brazil was U‐shaped, with middle‐income groups suffering larger proportional losses than the very poor. Nevertheless, as Brazil is 80% urban, higher food prices still led to a greater incidence and depth of poverty at the national level.  相似文献

A new multi-logistic methodology to analyze long range time series of evolutionary S-shaped processes is presented. It conceptually innovates over the traditional logistic approach. The ansatz includes computing the residuals to an optimized multi-logistic trend curve least squares fitted to the time-series data. The elements of the residuals series are checked for autocorrelations and once detected the residuals series is further analyzed to search for eventual presence of underlying periodic structures using a truncated Fourier sine series. The method foundations ensures both a universal applicability and a capacity to disclose the existence of active clocks that can be possibly traced to the driving motors of the evolutionary character of the time series, due to the responsiveness of corresponding process to the development of economic cycles. On associating these two views, it is found that the methodology has a strong potential to improve the quality of short-term forecasts. These findings have been put to test through applications of the methodology to studying the time evolution of two commodities of strong economic and social importance (corn and steel) and good results were consistently obtained for both the analytical and forecasting aspects.  相似文献

The endogeneity of prices has long been recognized as the main identification problem in the estimation of marginal willingness to pay (MWTP) for the characteristics of a given product. This issue is particularly important in the housing market, since a number of housing and neighborhood features are unobserved by the econometrician. This paper proposes the use of a well defined type of transaction costs–moving costs generated by property tax laws–to deal with this type of omitted variable bias. California's Proposition 13 property tax law is the source of variation in transaction costs used in the empirical analysis. Beyond its fiscal consequences, Proposition 13 created a lock-in effect on housing choice because of the implicit tax break enjoyed by homeowners living in the same house for a long time. Its importance to homeowners is estimated from a natural experiment created by two amendments that allow households headed by an individual over the age of 55 to transfer the implicit tax benefit to a new home. Indeed, 55-year old homeowners have 25% higher moving rates than those of comparable 54 year olds. These transaction costs from the property tax laws are then incorporated into a household sorting model. The key insight is that because of the property tax laws, different potential buyers may have different user costs for the same house. The exogenous property tax component of this user cost is then used as an instrumental variable. I find that MWTP estimates for housing characteristics are approximately 100% upward biased when the choice model does not account for the price endogeneity.  相似文献
