Disability Risk Management and Postinjury Employment of Workers With Back Pain

We analyze the outcomes of occupational back pain among four large employers that use one or more of the following disability management practices: aggressive return to work, claims management, medical management, or time‐limited job accommodations. Outcomes measured at 6 and 12 months postonset include: duration of initial work absence and the probability of returning to stable employment. Employment outcomes are better in firms with more proactive return‐to‐work policies than in firms with more restrictive policies. We devise a statistical test for attrition bias and conclude that sample attrition does not significantly alter our results.     

How large is liquidity risk in an automated auction market?

We introduce a new empirical methodology that models liquidity risk over short time periods for impatient traders who submit market orders. Using Value-at-Risk type measures, we quantify the liquidity risk premia for portfolios and individual stocks traded on the automated auction market Xetra. The specificity of our approach relies on the adequate econometric modelling of the potential price impact incurred by the liquidation of a portfolio. We study the sensitivity of liquidity risk towards portfolio size and traders' time horizon, and interpret its diurnal variation in the light of market microstructure theory.

Asset Prices as Indicators of Euro Area Monetary Policy: An Empirical Assessment of Their Role in a Taylor Rule

This paper estimates forward-looking and forecast-based Taylor rules for France, Germany, Italy, and the euro area. Performing extensive tests for over-identifying restrictions and instrument relevance, we find that asset prices can be highly relevant as instruments in policy rules. While asset prices improve Taylor rule estimates, different assets prove most relevant across countries and this result could be seen as complicating the tasks of the European Central Bank. Encompassing tests show that forecast-based outperform forward-looking Taylor rules. A policy implication is that central banks ought to release their own forecasts and the basis upon which they are generated.

Natural Disaster Insurance and the Equity-Efficiency Trade-Off

This article investigates the role of private insurance in the prevention and mitigation of natural disasters. We characterize the equity‐efficiency trade‐off faced by the policymakers under imperfect information about individual prevention costs. It is shown that a competitive insurance market with actuarial rate making and compensatory tax‐subsidy transfers is likely to dominate regulated uniform insurance pricing rules or state‐funded assistance schemes. The model illustrates how targeted tax cuts on insurance contracts can improve the incentives to prevention while compensating individuals with high prevention costs. The article highlights the complementarity between individual incentives through tax cuts and collective incentives through grants to the local jurisdictions where risk management plans are enforced.     

Why not fully spend a conditional block grant?

This paper studies a conditional block grant that Dutch municipalities receive for welfare-to-work programs. Many municipalities do not fully use this grant, although programs are beneficial for them. We argue that municipalities incur expenses to use the grant. If these costs are substantial, then it is optimal not to fully use the grant. Based on municipality-specific data on grants and actual expenditures, we estimate that municipalities have to add about 90 cents from their own resources to spend 1 euro of the grant. As a result, the conditional block grant is de facto a closed-ended matching grant.     

FAIR RETIREMENT UNDER RISKY LIFETIME*

A premature death unexpectedly brings a life and a career to their end, leading to substantial welfare losses. We study the retirement decision in an economy with risky lifetime and compare the laissez‐faire with egalitarian social optima. We consider two social objectives: (1) the maximin on expected lifetime welfare, allowing for a compensation for unequal life expectancies, and (2) the maximin on realized lifetime welfare, allowing for a compensation for unequal lifetimes. The latter optimum involves, in general, decreasing lifetime consumption profiles as well as raising the retirement age. This result is robust to the introduction of unequal life expectancies and unequal productivities.     

Hidden costs of supply management in a small market

Canada regulates its dairy and poultry industries through supply management. The supply‐management programs use target prices, production quotas and import tariff‐rate quotas to raise domestic prices. Canadian supply‐managed producers cannot export their output to world markets as exports would be considered subsidized under World Trade Organization rules. In this paper, we show that once foregone export opportunities are accounted for, supply management may no longer be beneficial to domestic producers of the supply‐managed commodities. The extent to which foregone profits from exports dominate domestic rents depends on Canada's comparative advantage, domestic market elasticities and the extent of supply management distortion in the domestic market.     

Career and collaboration patterns in tourism research

Research collaboration has become an important characteristic of contemporary academia and is of prime importance for the academic career opportunities of young scholars. For the purposes of this study research collaboration is a formal manifestation of intellectual collaboration in scientific research and involves the participation of two or more authors in the production of a joint publication. The paper reports the findings of a quantitative online survey sent to tourism scholars to explore their career and collaboration patterns in co-authored publications in tourism research. The results indicate that there are divergent perspectives on research collaboration and that collaboration characteristics change as scholars progress through their careers. The paper proposes a research career lifecycle to explain the patterns in tourism research collaboration.     

Accounting students’ choice of blended learning format and its impact on performance and satisfaction

Using online platforms to deliver educational content, some institutions have developed blended courses that combine the advantages of online instruction with traditional face-to-face (F2F) teaching. This study compares accounting student performance and satisfaction in two blended formats with similar content and design, i.e. F2F+ vs. Online+ courses. It also assesses the characteristics of students who choose the latter option over F2F+ courses. Students in four advanced accounting subjects were surveyed and their course performance was obtained. Results indicate that the main determinants of students’ decision to register for an Online+ course are retaking the course, increased weekly work hours, and belief that this type of blended course facilitates learning. Results show that students in advanced accounting courses with equivalent content and design perform similarly and have the same level of course satisfaction across course delivery formats, as hypothesized under equivalency theory.
