Overlapping Generations and Environmental Policy： An Introduction

A small but growing body of literature uses overlapping generations （OLG） models to study environmental policy for long-lived problems such as climate change. An OLG model, unlike the infinitely lived representative agent model, dis- tinguishes between impatience with respect to one＇s own future utility, and attitudes toward successors＇ utility. I discuss the problem of time inconsistency, the role of Markov perfection, and show that a class of OLG models can be studied using me- thods developed to analyze models of non-constant discounting. An example illu- strates the techniques and determines the conditions under which, in equilibrium, there is under-investment or over-investment in natural capital.     

Tariffs and formation of free trade agreements networks

This paper examines the formation of bilateral free trade agreements (FTAs) on the basis of country heterogeneity in the tariff level. We demonstrate that a country's unilateral incentive to form an FTA depends on the relative magnitudes of the (negative) market concession effect and the (positive) market expansion effect, both of which are determined by the tariff levels of the two FTA partner countries. Global welfare is maximised when all country pairs form FTAs. Two countries in equilibrium are more likely to form an FTA when their tariff gap is smaller or when their tariff levels are neither very high nor very low. This finding is robust to several extensions of the model. Our preliminary empirical analysis provides some evidence for the finding.     

Beyond trade creation: Preferential trade agreements and trade disputes

This study investigates the effects of preferential trade agreements (PTA) on bilateral trade disputes. We construct a unique and comprehensive dataset on inter-country trade disputes from 1995 to 2007. The dataset covers 110 countries and 1,162 bilateral country-pair trade disputes. Using this dataset in a gravity-type model of trade dispute analysis, we find that countries belonging to the same PTA tend to experience fewer trade conflicts among themselves than with non-member countries. By studying various types of PTA with different dispute settlement mechanisms, we further find that the dispute-reducing effect only comes from PTA with specific provisions on dispute settlement mechanisms. Moreover, the effect is stronger if those PTA explicitly stipulate that members can also resolve their disputes via the WTO Dispute Settlement Body. However, having PTA that do not address how members should resolve their disputes may lead to more dispute initiations than in cases without PTA.     

Financial functional analysis: a conceptual framework for understanding the changing financial system

The financial system is currently undergoing a revolution brought about by e-finance, digital convergence, new market entrants and government-encouraged competition. New market entrants such as Apple, Alibaba, Facebook and Google come from industries such as IT, retail, social media and telecoms, and, therefore, do not fit comfortably within traditional financial institutional structures. A functional perspective might provide more practical insights into this revolution; however, the functional perspective has had a limited impact. This paper will investigate the benefits and limitations of financial functional analysis; probe the underpinning principles of sociology’s structural functional analysis; revisit Merton and Bodie’s (1995) six core financial functions in relation to new entrants in the financial landscape; and, finally, argue that in the new financial environment, functional analysis provides a more coherent and explanatory framework of the financial system for students and practitioners alike.     

Determinants of restaurant's owners/managers selection of wines to be offered on the wine list

The aim of the paper is to better understand wine list design in restaurants in four countries with very different wine cultures. An interview protocol was developed and administered to 286 restaurants across the four countries (France, Australia, USA and China). The interview questionnaire included a Best/Worst methodology to identify the most/least important factors influencing the restaurant's owner/manager's selection of wine for the wine list. One of the most important reasons for selecting wine across most countries is ‘to match wine with the food menu’. There were few major differences between countries, but a latent class analysis found four clusters that differed significantly with membership also differing between countries. The cluster analysis also indicated that while some restaurateurs are more brand-driven, others value local wine or its matching with the food menu.     

The cost of quality in existing housing: Estimates from an implicit markets model

Rosen's implicit markets approach is used to model and estimate the cost of improving the state of repair of rental housing in existing structures. Particular attention is devoted to potential errors in the measurement of state of repair and to the inconsistent estimates of supply and demand parameters implied by Rosen's original econometric technique. Cost estimates imply that improvements in low-income housing could be provided much less expensively in existing housing than by either public new construction or the Section 8 existing housing program.     

Achieving the Sustainable Development Goals: improving water services in cities affected by extreme weather events

Abstract

This article discusses how key risks from extreme weather events might affect progress towards meeting Sustainable Development Goals 6 and 11 in cities in developing countries. It outlines the magnitude of the existing shortfall in safe water and sanitation services, and how climate change will exacerbate existing problems. It argues that the performance of many governments thus far has lacked urgency and purpose. Unless governments in particular become more committed, with redoubled effort, the goals are unlikely to be achieved.     

Selected Current Data Sources

This identifies the major sources for current economic data. Most of the publications are free; many others are inexpensive. Instructors can use them to update textbooks, and students will find them useful for databases for simulation models, papers, and reports.
