Textbook Treatments of the Financial Market in the IS-LM Model

Intermediate macroeconomics textbooks introduce financial markets into the IS-LM analysis but typically as a beginning-of-period consideration. Here the financial market is introduced in an end-of-period model.

Preferences and Willingness to Pay for Green Hotel Attributes in Tourist Choice Behavior: The Case of Taiwan

Although many companies in the hotel industry aim to pursue more sustainable and socially responsible practices, the present literature shows mixed results with regard to tourist reactions to such moves, especially for the service quality perception impacted by implemented green practices and the willingness to pay more for such actions. Unlike previous research examining tourists’ preferences for separate green hotel attributes, this study identifies the determinants of tourists’ choice of green hotel attributes. Additionally, the study measures the willingness to pay (WTP) for such services, in the context of the Taiwanese market, using the stated preference of combined green hotel attribute scenarios. A multinomial logit (MNL) model is employed to estimate the relative influence of behavioral and facility attributes on choice behavior. Furthermore, the study examines determinants influencing respondents’ choice of green hotel attributes. A latent variable class model (LVCM) approach is applied in the estimation of the unobserved heterogeneity, and a total of 390 valid respondents were used in the analysis. The empirical MNL results indicate that while tourists prefer luxury rooms and the provision of personal toiletries, they are also willing to accept reduced service quality. Additionally, sex, income, and age have significant influences on tourist choice behavior. The results of the LVCM model demonstrate that respondents with high levels of the green consumption trait are more likely to choose hotels that have a greater number of environmentally friendly attributes. The implicit amount that tourists are willing to pay for room quality is around US$13, for the provision of personal toiletries is about US$22, and for service quality is US$12, but they also require a discount of approximately US$11 in order to accept the common practices of green hotels. This study is useful in providing the hotel industry and government with quantitative information that can be used to develop and implement better green hotel policies.

Teaching the Minimum Wage in Econ 101 in Light of the New Economics of the Minimum Wage

The author argues that the recent controversy over the effect of the minimum wage on employment offers an opportunity for teaching introductory economics. Research findings on the minimum wage could be used to motivate alternative models of the labor market, such as monopsony and search models, and to teach students how economists test hypotheses with data.

Temporal stability of preferences and willingness to pay for natural areas in choice experiments: A test–retest

The main objective of this paper is to test the temporal stability of stated preferences and willingness to pay (WTP) values from a Choice Experiment (CE) in a test–retest. The same group of participants was asked the same choice tasks in an internet-based CE, conducted twice with a time interval of one year without interviewer interference. We examine choice consistency at individual choice task level and transferability of the underlying indirect utility function and associated WTP values. The results show that choices are consistent in 57 percent of the choice occasions. Comparison of the choice models over time shows that the estimated preference and scale parameters are significantly different, suggesting that choice behaviour changed between the two surveys. Differences between marginal WTP estimates for individual choice attributes are statistically significant only at the 10 percent level. However, we show that this can result in significantly different WTP values for policy scenarios. The instability of estimated mean WTP values for different policy scenarios asks for caution when including WTP values in cost-benefit analysis.
