ECONOMIC GROWTH, INCOME AND HAPPINESS: AN EXPLORATORY STUDY

The pursuit of high economic growth is considered desirable as it generates an increase in a nation's wealth, income, employment and output. The rising income should enable consumers to purchase more goods and services, which in turn should result in enhanced utility and subjective happiness. Empirical studies suggest that higher income resulting from high rates of economic growth contribute to poverty alleviation and life satisfaction in low income countries. Higher income raises the happiness of the poor. In developed countries, higher income does not seem to buy higher happiness, once a threshold level of income is reached. This exploratory study seeks to examine the quantitative and qualitative sources of happiness. A higher absolute level of income is found to be significantly related to subjective happiness. Among the non-income factors, family togetherness, a good working environment and a higher level of education can contribute to making people happier. Happiness thus involves more than just economic growth and income.     

TREATMENT EFFECTS OF CLIMATE CHANGE RISK ON MITIGATION AND ADAPTATION BEHAVIOUR IN AN EXPERIMENTAL SETTING*

This paper explores the collective action problem as it relates to climate change and develops two models that capture the mitigation–adaptation trade‐off. The first model presents climate change as a disaster that will occur with certainty, and where both mitigation and adaptation reduce the size of the loss associated with the disaster (the so‐called deterministic model). The second model presents climate change as an uncertain event, where mitigation affects the probability of disaster while adaptation again reduces the size of the loss (this is the so‐called stochastic model). Comparing the two models in a one‐shot public goods experiment with students, we find no significant differences in subjects' choice to mitigate. The experiments also reveal a relatively low rate of mitigation for both models compared with earlier studies.     

CIGARETTE DEMAND IN SOUTH AFRICA OVER 1996-2006: THE ROLE OF PRICE, INCOME AND HEALTH AWARENESS

The study seeks to re‐investigate the role of price, income and health awareness in the evolution of South African cigarette demand over the period 1996 to 2006. At first glance, rising cigarette prices appear to have played an important role in reducing cigarette consumption over the sample period, especially during the late 90s. But how dependent is the impact of price increases on general economic conditions and overall health awareness among smokers? Health awareness, in particular, has not received sufficient attention in the South African context, due to a lack of data. Previous estimates of price and income elasticities of cigarette demand are based on long annual time series data, which do not allow for changes in underlying tastes and preferences. The paper attempts to disentangle the forces of price, income, health awareness and policy intervention using a quarterly data set. In addition, the study also cautions against the upward bias in estimates derived from formal cigarette sales data – in the light of increasing illicit cigarette volumes in South Africa.     

NEW ESTIMATES OF AUSTRALIAN PUBLIC BORROWING AND CAPITAL RAISED IN LONDON, 1849–1914

Current statistics of Australian public borrowing to 1914 suffer from several limits. On the basis of a comprehensive revision, an upward bias is shown in all the alternative time series of London borrowing, while statistics of local bond issues are derived for the first time. The new time series show the importance of the initial borrowing cycle during the 1850s and 1860s; the scale of debt repatriation from the mid-1890s; the interaction between domestic and overseas borrowing before the 1880s; and the potential significance of remittance as an 'invisible stabiliser' of the exchanges and alternative indirect source of capital imports.     

AN ALTERNATIVE PERSPECTIVE ON SOUTH AFRICA'S PUBLIC DEBT, 1962‐1994

The history of public debt reflects the cumulative effect of fiscal decisions and real outcomes in the economy. In the South African case the published record on public debt distorts the historical perspective on the associated fiscal decisions. This paper shows the impact of adjusting the South African public debt on an accrual basis to take account of two major obligations assumed in the first half of the 1990s, namely actuarial pension fund deficits and government debt of the apartheid homelands. The adjusted series is less volatile and rose less steeply between 1989 and 1996 than the official, cash‐based debt series. Failing to account for the evolution of these obligations exaggerates the impression of weak fiscal discipline in the early 1990s and exemplary fiscal prudence in preceding decades.     

Regulating the Anticommons: Insights from Public‐Expenditure Theory

This article offers a new interpretation of the traditional Cournot complements problem, or anticommons, by using the theory of public goods to gain a perspective on the problem. Specifically, I examine the pricing strategies and regulation of multiple monopolies that produce products which consumers view as perfect complements. I show that collusion by the firms increases total social welfare and that the collusion problem can be reinterpreted as a problem of provision of public goods from the point of view of the firms. I take this insight further and derive the familiar concepts of the Samuelson marginal condition and the ratio equilibrium for the firms. I compare these outcomes to the first best solution and then apply incentive‐compatible mechanisms to strategically implement the Pareto superior ratio‐equilibrium outcome and the optimal marginal‐cost pricing outcome. Finally, I show how this methodology can be applied to the more familiar Cournot model of oligopoly.     

The Max‐Min Group Contest: Weakest‐link (Group) All‐Pay Auction

We investigate a group all‐pay auction in which each group's effort is represented by the minimum among the effort levels exerted by the group members and the prize is a group‐specific public good. We fully characterize the symmetric equilibria for two groups. There are four types of equilibria: the pure strategy equilibria in which all (active) players exert the same effort; the semi‐pure strategy equilibria in which the players in a group play the same pure strategy whereas those in the other group play the same mixed strategy; the nondegenerate mixed strategy equilibria with continuous support; and the nondegenerate mixed strategy equilibria with discontinuous support. We then analyze a general contest with n groups.     

Private Goods,Public Goods,and Common Pools with Homo Reciprocans

Familiar inefficiencies arise with competing interests over private goods in Stackelberg and investment games. Private good experiments reveal whether reciprocity enhances cooperative outcomes. Familiar social dilemmas arise with voluntary provision of public goods and voluntary appropriation from common pools. Experiments with pairs of payoff‐equivalent provision and appropriation games reveal whether reciprocity is more or less effective in ameliorating under‐provision or over‐appropriation. Experiments with asymmetric provision and appropriation games also yield insight into the effects of the Indian caste system on inefficiency from social dilemmas. Experiments with three types of games, with a private good, public good or common pool, provide diagnostic tests of the homo reciprocans model.     

Economics,Insurance, and Flood Hazards

This article introduces the Symposium Economics, Insurance, and Flood Hazards. We provide background on the magnitude of recent extreme weather events and subsequent flooding in terms of lives and property damage. After a brief background of the National Flood Insurance Program and its renewal, we describe the papers contributed to the symposium and their relationship to the challenges described by the U.S. General Accountability Office (GAO).     

Exploiting the Chaos: Terrorist Target Choice Following Natural Disasters

This article explores the differences between transnational and domestic terrorism, further differentiating by private versus government targets, to estimate the effect of exogenous catastrophic shocks on a country's level of domestic and transnational terrorism. The empirical analysis uses detailed data on terrorism, natural disasters, and other relevant controls for 176 countries from 1970–2007 to illuminate several key disparities in a postdisaster target choice of terrorists. The results indicate that natural disasters incite both transnational and domestic terrorism; however, evidence is found for dissimilar motivations between the two. While both types of terrorism increase after disasters, transnational attacks against the government increase immediately following the disaster, suggesting an impetus to exploit weakened “hard” targets during the chaos. Conversely, domestic terrorism against the government takes longer to manifest, suggesting a period of time for which the public recovers and assesses the government's response.     

EFFECTS OF IMPROVING INFRASTRUCTURE QUALITY ON BUSINESS COSTS: EVIDENCE FROM FIRM‐LEVEL DATA IN EASTERN EUROPE AND CENTRAL ASIA

Public infrastructure is one of the important determinants of economic growth. Not only access to but also quality of infrastructure affects firm productivity as well as people's livelihood. Frequent interruptions of the infrastructure‐service supply impose extra backup costs on enterprises, hinder their timely business activities, and result in large losses of sales opportunities. This paper focuses on the impacts of improving the quality of public utilities (electricity, water supply, and telecommunications), using firm‐level data from 26 transition economies in Eastern Europe and Central Asia. The results suggest that firm costs would significantly increase when electricity outages occur frequently and the outage duration becomes longer. Similarly, when more time is required to restore suspended water supply, firms' competitiveness would be weakened. Not surprisingly, the impacts tend to vary depending on industry. The construction, manufacturing, and hotel and restaurant sectors are found particularly vulnerable.     

MACROECONOMIC PERFORMANCE AND INEQUALITY: BRAZIL, 1983–94

We examine how poor macroeconomic performance, mainly in terms of high rates of inflation, affected earnings inequality in the 1980s and early 1990s in Brazil. The results, based initially on aggregate time series, and then on sub‐national panel time‐series data and analysis, show that the extreme inflation, combined with an imperfect process of financial adaptation and incomplete indexation coverage, had a regressive and significant impact on inequality. The implication of the results is that sound macroeconomic policies, which keep inflation low and stable in the long run, should be a necessary first step of any policy package implemented to alleviate inequality in Brazil.     

WATER DEMAND AND THE URBAN POOR: A STUDY OF THE FACTORS INFLUENCING WATER CONSUMPTION AMONG HOUSHOLDS IN CAPE TOWN, SOUTH AFRICA

Water demand management is a key focus area for most water managers and even more so in developing countries since improved access to water is important to the poor. Different policies have been introduced to ensure a water management system th at cares for the poor, among them the Increasing Block Tariff (IBT) structure. Studies demonstrate that it is very important to know the shape of the demand curve when deciding on the IBT structure. This paper adds to the understanding of the factors that influence water consumption. The focus is on how water demand patterns vary with the level of income among urban dwellers. The results support the hypothesis that pricing is an ineffective measure to manage water consumption among the poor, while it is relatively more effective for the richest group. Therefore, redistribution using water pricing policy will hardly work.     

WILDLIFE MANAGEMENT IN ZIMBABWE: EVIDENCE FROM A CONTINGENT VALUATION STUDY

If communities living adjacent to the elephant see it as a burden, then they cannot be its stewards. To assess their valuation of it, a contingent valuation method study was conducted for one CAMPFIRE district in Zimbabwe. Respondents were classified according to their preferences over the elephant. The median willingness to pay for the preservation of 200 elephants is ZW$260 (US$4.73) for respondents who considered the elephant a public good and ZW$137 (US$2.49) for those favouring its translocation. The preservation of 200 elephants yields an annual net worth of ZW$10,828 (US$196) to CAMPFIRE households. However, the majority of households (62%) do not support elephant preservation. This is one argument against devolution of elephant conservation. External transfers constitute one way of providing additional economic incentives to local communities.     

FDI AND DOMESTIC INVESTMENT IN TAIWAN: AN ENDOGENOUS SWITCHING MODEL

The purpose of this paper is to examine the effect of the FDI decision on domestic investment in the case of Taiwanese manufacturing firms. In addition, we also consider the deferral effect of the FDI decision and the role of firm size. To this end, this paper takes advantage of an endogenous switching model from which consistent estimators are obtained after correcting for the self‐selection problem. The empirical results show that the effect of these manufacturing firms’ FDI decisions on domestic investment is significant within the firms. Furthermore, a crowding‐out effect of FDI on domestic investment is found when Taiwanese firms engage in defensive FDI. Finally, FDI is found to have a positive influence on the domestic investment of the larger firms, while the influence is negative in the case of the smaller firms.     

INFRASTRUCTURE QUALITY AND MANUFACTURING EXPORTS IN AFRICA: A FIRM‐LEVEL ANALYSIS

Using bilateral trade flow models, a body of empirical work has documented how geography and infrastructure variables affect trade performance. However, in this paper, we apply censored regression models like the Tobit and Probit on firm‐level manufacturing data from 10 African countries, and results suggest that inadequate infrastructure in the form of customs, transport, electricity and water negatively affects export intensity and participation. Owning a generator and private water source also appear to have a significant impact on exports. This, therefore, means that firms can minimise the impact of power and water disruption on production, and hence trade by installing these alternative energy and water sources.     

ECONOMIC EVALUATION OF THE PROPOSED ROAD BETWEEN GOBABIS AND GROOTFONTEIN,NAMIBIA

First, a cost‐benefit analysis is presented of reconstructing the existing road section between Gobabis and Otjinene in Namibia. Second, a cost‐benefit analysis is presented of constructing a new direct road link between Otjinene and Grootfontein, coupled with the above‐mentioned road upgrading between Gobabis and Otjinene as one project. The proposed link will shorten the existing route from Gobabis via Windhoek to Grootfontein by approximately 300 km. The following economic indicators are shown in the two cost‐benefit analyses: (i) Net Present Value, (ii) Benefit/Cost Ratio, and (iii) Internal Rate of Return. Third, the general economic impact that construction and operation of the entire road will have on non‐road users within Namibia is evaluated. This analysis is divided into two parts: The first part deals with the once‐off income‐multiplier effect triggered by the initial investment in the road, while the second part addresses the recurring income accelerator effect that usage of the road is expected to have within Namibia.     

GOVERNANCE INSTITUTIONS AND PRIVATE INVESTMENT: AN APPLICATION TO THE MIDDLE EAST AND NORTH AFRICA

This paper addresses the issue of the low level of private investment in the Middle East and North Africa (MENA) region, with special emphasis on the role of governance. Based on the existing published reports, we categorize what types of governance institutions are more detrimental to entrepreneurial investments. We then estimate a simultaneous model of private investment and governance quality where economic policies concurrently explain both variables. Our empirical results show that governance plays a significant role in private investment decisions. This result is particularly true in the case of “administrative quality” in the form of control of corruption, bureaucratic quality, investment‐friendly profile of administration, law and order, as well as for “political stability.” Evidence in favor of “public accountability” is also found. Our estimations also stress that structural reforms like financial development, trade openness, and human development affect private‐investment decisions directly, and/or through their positive effect on governance.     

STRUCTURE, CONDUCT AND PERFORMANCE ANALYSIS OF THE SOUTH AFRICAN AUTO INSURANCE MARKET: 1980-2000

The traditional structure-conduct-performance framework makes the explicit prediction that market structure determines market conduct, performance and power. The primary goal of this study is to evaluate this prediction using the South African (SA) short-term auto insurance market. The empirical evidence shows that a link between market structure and market conduct, performance and/or power is not present. Prices and profits are not statistically significantly related to various sellers' concentration measure and do not follow any explicit trend over time. By construction, profits are directly related to prices and follow a cyclical trend, as observed in other countries. A secondary goal of this paper is to compare the findings for the US auto insurance market with the empirical evidence on the SA auto insurance market. While there are few similarities, there is an underwriting cycle in the SA auto insurance market such as is observed for the US auto insurance market.     

MAKING THE COLONIAL STATE: DEVELOPMENT,DEBT, AND WARFARE IN NEW ZEALAND, 1853–76

Warfare in New Zealand during the 1860s has recently been linked to the rise of the central state and growth of the national debt in that colony. This article argues that any parallel to the growth of the European fiscal‐military state is misguided. The fundamental cause of state centralisation and rising indebtedness was the same long‐run dynamic of colonial development active in all settler societies during the nineteenth century. The colonial state functioned, in part, to raise capital for development, and if necessary the colonial state would be remodelled in order to achieve this. New Zealand was no exception.
