Why do many resource-rich countries have negative genuine saving?: Anticipation of better times or rapacious rent seeking

We investigate the Hartwick rule for saving of a nation necessary to sustain a constant level of private consumption for a small open economy with an exhaustible stock of natural resources. The amount by which a country saves and invests less than the marginal resource rents equals the expected capital gains on reserves of natural resources plus the expected increase in interest income on net foreign assets plus the expected fall in the cost of resource extraction due to expected improvements in extraction technology. Effectively, depletion is then postponed until better times. This suggests that it is not necessarily sub-optimal for resource-rich countries to have negative genuine saving. However, in countries with different groups with imperfectly defined property rights on natural resources, political distortions induce faster resource depletion than suggested by the Hotelling rule. Fractionalised societies with imperfect property rights build up more foreign assets than their marginal resource rents, but in the long run accumulate less foreign assets than homogenous societies. Hence, such societies end up with lower sustainable consumption and are worse off, especially if seepage is strong, the number of rival groups is large and the country does not enjoy much monopoly power on the resource market. Genuine saving is zero in such societies. However, World Bank genuine saving figures based on market rather than accounting prices will be negative, albeit less so in more fractionalised societies with less secure property rights.     

Financial Literacy and Preparation for Retirement

To meet the challenges of an ageing population, eligibility ages for state pensions have increased, early retirement arrangements have been abolished, and a substantial part of the risk and responsibility for an adequate standard of living after retirement has been shifted from the government, employers and pension funds to individuals and private households. Consequently, policy makers have become more concerned with whether individuals are able to make pension-related decisions that are in their own best interest.     

Job Search Behaviour and Time Preferences: Testing Exponential Versus Hyperbolic Discounting

This article examines the effects of time preferences on job search behaviour and tests the exponential versus the hyperbolic discounting model. Theoretically, the relations between time preferences and job search intensity, reservation wages and the exit rate depend on whether exponential or hyperbolic discounting is assumed. By analysing these relations empirically we test which model of intertemporal choice better explains the results. Using the DNB Household Survey, a Dutch longitudinal survey, we capture variation in time preferences by a psychological construct that measures an individual’s future orientation. The empirical results are consistent with the hyperbolic discounting model.     

Estimating social travel demand of senior citizens in the Netherlands

Like many other countries, the Netherlands is experiencing a sharp rise in the ageing population. As age increases, people’s mobility may decrease. However, older people have more leisure time compared to their younger (working) counterparts, and potentially spend more time on social activities. Therefore, this group can possibly increase social travel demand. However, to date, the travel demand for social activities of senior citizens has received only little attention. This paper studies trip-making for social purposes, with a special focus on the demographic ageing factors. Using social activity diary data, models are estimated to predict the number of social trips, the travel distance and mode of transport for social trips. The results indicate that the elderly of today seem to be as mobile as their younger counterparts with respect to the number of social trips. High education and involvement in clubs on average result in more social trips and full time work is found to result in fewer social trips. With regard to trip distance the results show that the average travel distance does not decrease as people get older. Full time work is found to result in longer social trips. Shorter trips were found for people in urban as well as rural areas. Trips for the purpose of visiting or joint activities tend to be longer than average. With regard to transport mode choice the results indicate that older seniors (75+) are less likely to choose the bicycle, relative to driving. No other significant age effects were found. Significant effects were found for gender, household structure, education level, car ownership, having a disability, urban density, distance and the purpose of the social activity.     

Non-monetary dimensions of well-being in South Africa, 1993–2004: A post-apartheid dividend?

Existing studies on shifts in income welfare in South Africa since the demise of apartheid suggest that income inequality increased, while headcount poverty rates declined since 2000, after some evidence of an increase or no change in poverty in the 1995–2000 and 1996–2001 periods. This study provides an analysis of the shifts in non-income welfare that have occurred in South Africa between 1993 and 2004. We use factor analysis to construct an asset index as a measure of non-income-based welfare. Variables reflecting household access to a range of services and assets are used in the construction of the index. Significantly different results emerge when non-income welfare shifts are considered: we show statistically significant decreases in the headcount asset poverty rates between 1993 and 2004 across a range of covariates. Finally, asset inequality decreased significantly between 1993 and 2004 – in stark contrast to results based on consumption data.     

Where firms choose to disclose voluntary environmental information

Corporate environmental performance is of increasing importance to investors, public policy makers and the general public. Firms disclose environmental information (mostly) voluntarily in their annual reports and on their websites. These disclosures are important, because they provide environmental performance information and influence capital markets. We compare environmental disclosure in annual reports and on websites with a long-term (bad) and a short-term (crisis) environmental performance measure. We find evidence to support our hypotheses that different levels of environmental disclosure are made in annual reports and on websites under different conditions. More specifically, firms disclose more environmental information on their websites when faced with an environmental crisis and more in their annual reports when they have a bad environmental reputation.     

The interplay of governance mechanisms in complex procurement projects

Although many studies have investigated governance in inter-firm relationships, little is known about the simultaneous use of several governance mechanisms in complex procurement projects and their impact on project outcomes. In a case study about a complex procurement project in the Norwegian oil and gas industry, we investigate the interplay of contractual incentives, authority and relational governance. The project faced many problems with cost overruns and schedule delays. The study clearly illustrates the interrelationships between governance mechanisms and their effect on project outcomes. The findings suggest that relational governance (trust) is only beneficial for project outcomes when it is accompanied by contractual incentives and control systems (authority). Relational governance in itself does not guarantee an effective and beneficial interplay of all three mechanisms in a way that positive project outcomes are generated.     

Repeated audit controls

An important task of auditors is to check whether recorded values are correct. From the number (or total) of the errors found in a sample, upper confidence limits for the fraction (or total) of the errors in the population are calculated by standard methods.
Even auditors are human, however, and may make mistakes: errors may remain unnoticed. As administrative rules and regulations are becoming more and more complicated, this kind of auditors' mistakes tends to occur more frequently. Hence, there is an increasing need to check the auditing process itself. This can be achieved by checking a subsample of audited values a second time, now by an error-free supervisor.
This paper investigates the consequences of the (possible) occurrence of errors in this subsample. A simple and analytically attractive model is presented for the number of errors found in this double inspection scheme. Maximum likelihood estimators are derived for the population fraction of errors and the probability of an error remaining unnoticed. Based on that, an exact upper confidence limit for the population fraction of errors is calculated, treating the probability of an unnoticed error as a nuisance parameter. Our method was originally developed during a recent Dutch case study: in a subsample of already audited values one additional error was found by the supervisor. It is shown that, as a consequence, the upper confidence limit is increased very sizeably.     

Predicting early adoption of successive video player generations

Early adopters play an important role in the innovation diffusion process. Over the past decades, many factors have been identified as predictors for early adoption of innovations. Less attention has been paid to the relationship between the early adoption of one generation of a specific product and the early adoption of successive product generations. This paper analyzes how early adoption of a new product generation depends on ownership, purchase experience and adoption times for previous generations of the same product. The paper develops predictive models of early adoption for four generations of video player products, based on a survey among 815 Australian consumers. The model allows the testing of various hypotheses. It is shown that previous generation variables outperform conventional socio-demographic and psychographic variables in predicting early adoption but also that the two variable types complement each other. The best predicting models include both previous generation and socio/psychographic variables. It is concluded that previous generation models have substantial merits for new product forecasting as they are more parsimonious than conventional models and the data required to estimate them is relatively easy to obtain.
