Do pensions foster education? An empirical perspective

The paper examines the effect of population ageing on public education spending. On the one hand, ageing is expected to have a negative effect on education, as an increasing number of retirees results in ‘intergenerational conflict’ and, hence, the condemnation of education expenditure. On the other hand, ageing, in combination with pay-as-you-go pension systems, offers incentives for the working-age generation to invest in the public education of the young in order to ‘reap’ the benefits (that is, higher income tax/contributions) of their greater future productivity. Empirical evidence derived from the application of a fixed effects approach to panel data for OECD countries shows that the increasing share of elderly people has a non-linear effect on education spending. This indicates a certain degree of intergenerational conflict. Nevertheless, we find that future population ageing, which reinforces the mechanism linking public education and pensions, reflects positively on education expenditure. Furthermore, by disaggregating total education expenditure by educational levels, we observe that this effect is led by levels of non-compulsory education, probably as a reflection of the direct connection to labor productivity.     

The costs of non-tariff barriers to trade: Evidence from New Zealand

The Costs of Non-Tariff Barriers to Trade: Evidence from New Zealand. — Recent work on trade policy with imperfect competition indicates that the adverse effects of non-tariff barriers to trade exceed those suggested by traditional theory. With market power in foreign supply, setting a restrictive non-tariff barrier will induce foreign exporters to raise their supply prices. The authors use the experiment provided by the comprehensive New Zealand economic reforms of the mid-1980s. Using panel data on export unit values from Germany and the United States to several destinations including New Zealand, they find some evidence for decreased export prices to New Zealand as a result of the dismantling of non-tariff barriers to trade.     

Measuring Integrated Market and Credit Risk in Bank Portfolios: An Application to a Set of Hypothetical Banks Operating in South Africa

The banking crises of the ‘90s emphasize the need to model the connections between financial environment volatility and the potential losses faced by financial institutions resulting from correlated market and credit risks. Due to the number of variables that must be modeled and the complexity of the relationships an analytical solution is not feasible. We present here a numerical solution based on a simulation model that explicitly links changes in the relevant variables that characterize the financial environment and the distribution of possible future bank capital ratios. This forward looking quantitative risk assessment methodology allows banks and regulators to identify potential risks before they materialize and make appropriate adjustments to bank portfolio credit qualities, sector and region concentrations, and capital ratios on a bank by bank basis. It also has the potential to be extended so as to assess the risks of correlated failures among a group of financial institutions (i.e., systemic risk analyses). This model was applied by the authors to the study of the risk profile of the largest South African Banks in the context of the Financial System Stability Assessment program undertaken by the IMF in 1999. In the current study, we apply the model to various hypothetical banks operating in the South African financial environment and assess the correlated market and credit risks associated with business lending, mortgage lending, asset and liability maturity matches, foreign lending and borrowing, and direct equity, real estate, and gold investments. It is shown to produce simulated financial environments (interest rates, exchange rates, equity indices, real estate price indices, commodity prices, and economic indicators) that match closely the assumed parameters, and generate reasonable credit transition probabilities and security prices. As expected, the credit quality and diversification characteristics of the loan portfolio, asset and liability maturity mismatches, and financial environment volatility, are shown to interact to determine bank risk levels. We find that the credit quality of a bank's loan portfolio is the most important risk factor. We also show the risk reduction benefits of diversifying the loan portfolio across various sectors and regions of the economy and the importance of accounting for volatility shocks that occur periodically in emerging economies. Banks with high credit risk and concentrated portfolios are shown to have a high risk of failure during periods of financial stress. Alternatively, banks with lower credit risk and broadly diversified loan portfolios across business and mortgage lending are unlikely to fail even during very volatile periods. Asset and liability maturity mismatches generally increase bank risk levels. However, because credit losses are positively correlated with interest rate increases, banks with high credit risk may reduce overall risk levels by holding liabilities with longer maturities than their assets. Risk assessment methodologies which measure market and credit risk separately do not capture these various interactions and thus misestimate overall risk levels.     

Working towards sincere encounters in volunteer tourism: an ethnographic examination of key management issues at a Nordic eco-village

This article explores host–guest dynamics at Sólheimar eco-village, Iceland to contribute to the conceptualization of transformative learning in volunteer tourism. At the eco-village, the host and volunteers come together to share similar goals and meaningful experiences. This interaction gets complicated, however: the eco-village exists within the global capitalist system and must operate using market norms. The idealist and educational expectations of the volunteers often clash with the practical short-term goals of the community: there are also cultural and experiential differences between the parties. This clash is used to discuss the importance of sincerity in volunteer tourism at the eco-village. Data were collected through fieldwork, primarily including participant observations and interviews, to help interpret the patterns of behaviors and perceptions of both parties in relation to the aim. Ultimately, the experience that binds host and guests cannot solely be about learning to do things alternatively and sustainably; it requires sincerity, using Taylor's 2001 sincerity concept, to tackle the difficulties in working alternatively and sustainably to attain this experience. It is argued that transformative learning during the volunteer experience in alternative spaces should be conceptualized to include the promotion of sincere encounters, and adjusted to concern both the host and its guests.     

The role of stochastic volatility and return jumps: reproducing volatility and higher moments in the KOSPI 200 returns dynamics

This paper investigates the role of stochastic volatility and return jumps in reproducing the volatility dynamics and the shape characteristics of the Korean Composite Stock Price Index (KOSPI) 200 returns distribution. Using efficient method of moments and reprojection analysis, we find that stochastic volatility models, both with and without return jumps, capture return dynamics surprisingly well. The stochastic volatility model without return jumps, however, cannot fully reproduce the conditional kurtosis implied by the data. Return jumps successfully complement this gap. We also find that return jumps are essential in capturing the volatility smirk effects observed in short-term options.

Strategic Commitment and Timing of Internationalization from Emerging Markets: Evidence from China,India, Mexico,and South Africa

In a study of 257 new ventures from China, India, Mexico, and South Africa, we find support for the mediating effect of strategic early internationalization on international sales intensity. We argued that when new ventures from emerging markets internationalize early and with commitment, the legitimacy they acquire helps them overcome liabilities of newness and foreignness. We develop a typology of international new ventures that, based on strategic intent and timing of internationalization, distinguishes strategic early internationalizers from persistent, serendipitous, and long‐term internationalizers. We show that strategic early internationalization accounts for over half of the explained variance in international sales intensity and either fully or partially mediates the effects of managerial knowledge and market orientation on international sales intensity.     

Reflections on discriminant validity: Reexamining the Bove et al. (2009) findings

Bove, Pervan, Beatty and Shiu (2009) develop and test a latent variable model of the role of service workers in encouraging helpful behaviors by customers towards the service business (OCBs). Farrell (2010) questions these findings due to an incorrect application of the Fornell and Larcker (1981) discriminant validity test. The authors respond to Farrell's criticism by discussing the options available for assessing discriminant validity, the current use of these options in top journals, the underlying assumptions of these assessments, and the appropriateness of the alternative assessments under different types of situations. Finally, the authors address the specific concerns raised in Farrell (2010) in regard to Bove et al. (2009).     

Mobility of public researchers, scientific knowledge transfer, and the firm's innovation process

The present study provides evidence on the mobility effects of researchers from the public R&D system with regard to firm's innovation process. This issue is particularly novel and important as these researchers contribute to the production and transfer of knowledge previously developed and accumulated in the public R&D system. The findings confirm that scientific knowledge which public researchers provide has a positive influence on both inputs and outputs of the firms' innovation process. The fact that firms have access to additional knowledge which is complementary to that they already hold represents a spur for exploiting and applying this new knowledge. The firms in this study continually increased their in-house R&D investments. As a result of these investments firms create new knowledge of a unique and valuable type. The study draws two important conclusions geared to providing a greater efficiency in human resource management and to improve the design of technology policies.
