First-Order Mortality Basis for Life Annuities

Mortality improvements pose a challenge for the life annuity business. For the management of such portfolios, it is important to forecast future mortality rates. Standard models for mortality forecasting assume that the force of mortality at age x in calendar year t is of the form exp, where the dynamics of the time index is described by a random walk with drift. Starting from such a best estimate of future mortality (called second-order mortality basis in actuarial science), the paper explains how to determine a conservative life table serving as first-order mortality basis. The idea is to replace the stochastic projected life table with a deterministic conservative one, and to assume mutual independence for the remaining life times. The paper then studies the distribution of the present value of the payments made to a closed group of annuitants. It turns out that De Pril–Panjer algorithm can be used for that purpose under first-order mortality basis. The connection with ruin probabilities is briefly discussed. An inequality between the distribution of the present value of future annuity payments under first-order and second-order mortality basis is provided, which allows to link value-at-risk computed under these two sets of assumptions. A numerical example performed on Belgian mortality statistics illustrates how the approach proposed in this paper can be implemented in practice.     

Walking a slippery line: Investments in social values and product longevity

Corporate sponsorship of events that support social values (e.g., human rights) help firms infuse their products with symbolic meaning, prolonging their life cycle. Yet, higher product prices might spark perceptions that the firm invests in social values for calculative or opportunistic motives, in which case event sponsorship is unlikely to deliver the expected benefits in the form of product longevity. This study explores this potential tension empirically, using data related to sponsored social events, entry prices, and product longevity for a U.S. cosmetics producer.

Industrial restructuring in Russia: early reactions fo firms to the shock of liberalization1

This paper looks at the reaction of Russian firsm to the shock of liberalization. Firms are exposed to two kinds of shocks. A supply affects their profitability. A demand shock reflects the new expression of consumers and the opening of the country to foreign competition. Econometric tests show that firms adapt to these changes. They react by adjusting their output. They are not able to change their production techniques for lack of fresh capital. Employment is more stable that output: it is preserved by the adjustment of real wages. Therefore, firms with a low share of material inputs are relatively better off.     

Eigenerzeugung und Selbstverbrauch von Strom – Stand,Potentiale und Trends

Due to falling costs of self-production, increasing end-user electricity prices as well as indirect state incentives, self-production and consumption of electricity have become more and more attractive for end-users across all economic sectors. Thus, opportunities to evade taxes, surcharges and grid charges have arisen under the current legal framework. The situation is complicated by unclear requirements for the utilisation of state incentives as well as the vague statistical coverage of self-consumption. Historically, the total amount of self-consumption rose by 26?% between 2008 and 2012 to 56.7 TWh. The estimation of economic potentials and trends shows that development could accelerate substantially to a point where a considerable amount of the consumption in all sectors could be covered by self-production. This development will be significantly determined by the future legal framework regarding taxation and surcharges for self-consumption. Besides the level of taxes and surcharges, the minimum limit for charging small generation units will be a key control variable. From an economical point of view, derogations lead to distorted competition between various technologies that causes inefficient production structures and distributional effects. Moreover, they create a self-reinforcing effect: The higher the self-consumption is, the lower the assessment base for apportionments and charges becomes, and the higher the cost burden for the remaining end-users will be. As a result, the incentives for self-consumption are enhanced and, once again, the increased self-consumption causes further economic inefficiencies.     

How does competition among lodging sharing platforms affect welfare and profits?

We investigate the likely effect on prices, consumer surplus, and profits of intensified competition among peer‐to‐peer lodging platforms. We find that intensified competition in the sharing economy may give rise to some surprising results. For instance, intensified competition may allow platforms to charge higher fees from peer suppliers and lead, therefore, to a decline in consumer surplus. Only if the market of professional hoteliers is highly competitive, intensified competition among platforms leads to the traditional outcome that the entry of more platforms leads to lower fees charged from consumers and to enhanced consumer surplus. We also find that platforms may actually earn higher profits when there is intensified competition among professional hoteliers. In addition, while intensified competition among professional hoteliers leads to a decline in the fees that platforms can charge customers, it may actually result in higher lodging prices. We explain these counterintuitive results by the dual role that the lodging price plays in affecting the welfare of individuals active in the sharing economy. While a higher price has an adverse effect on the welfare of demanders of lodging it benefits peer suppliers of lodging because a higher lodging price raises the compensation they receive when offering lodging capacity to a platform.     

Allocative and distributional effects of a monopolistic cooperative firm in a capitalist economy

It is well known that labor-managed firms operating under socialism exhibit “bizarre” behavior with respect to their production strategy. We prove that under capitalism most of these distortions disappear, consequently, the production strategies of an entrepreneurial monopoly and of the labor-managed firm become indistinguishable. However, there appears an almost inherent instability in the distribution of profits. The degree of instability depends on the existence of some sort of supportive legislation. Thus, unlike under socialism, in a capitalistic economy the labor-managed firm may have an effect on the distribution of profits at most.     

Mergers and Exclusionary Practices in Health Care Markets

We evaluate the relationship between insurers (payers) and providers of health care (hospitals) when they each have a nonnegligible share of the market. We focus in particular on their incentives to merge and the existence of equilibria where payers offer preferential treatment to a subset of hospitals. We demonstrate that hospitals are more likely to merge without consolidating their capacities the less competitive they are vis-à-vis the payer's market. Payers are more likely to merge without consolidating their capacities the less competitive either the hospitals' or the payers' market is. A given payer follows an exclusionary strategy when its starting bargaining position vis-à-vis hospitals is weak. At such exclusionary equilibria, payers tend to distinguish themselves from neighboring payers by contracting with a different subset of hospitals.     

Disentangling the influence of internationalization on sustainability development: Evidence from the energy sector

This paper aims to deepen our understanding of the relationship between firms' internationalization and their sustainability development. We expected firms with a higher level of internationalization to exhibit better environmental management and performance. A sample of 287 publicly traded firms in the energy and energy‐related utilities sector was used to test these relationships. We focused on the energy sector, as energy production and supply have historically accounted for the lion's share of global greenhouse gas emissions. We found that firms' level of internationalization had a positive effect on their environmental management, whereas its effect on environmental performance was not found to be significant. We also tested whether these relationships change when firms' internationalization is oriented towards developing countries. Upon a closer look, the relationship was found to be significant between internationalization towards developing countries and better environmental management, thus contributing to the line of literature that does not support the pollution haven hypothesis.     

Performance evaluation,public management improvement and democratic accountability

The results-oriented management reforms fostered by the New Public Management movement are often argued to emphasize the search for efficiency, quality and other typical market values at the expense of democratic accountability. On the other hand, challenging this view, some authors claim that results-based management reforms have the potential to enhance political accountability and representative democracy. There is however, limited empirical evidence of this relationship. This article uses some of the findings from a comparative study of public management evaluation systems in four Latin American countries to illuminate this relationship in practice. We discuss the fact that, in two of the four countries surveyed, the design features of the new systems were based on the explicit search for increased political accountability and the deepening of democracy. We also discuss the possible causes for the finding that the outcome and performance information generated is not being applied for decision-making purposes yet, as expected.
