Österreichs Alterssicherung: Vorbild für Deutschland?

As a result of political reforms, pension provision in Germany is the task of a multi pillar model including private and occupational schemes in addition to the public pension insurance. By contrast, the Austrian single pillar model has been developed into an encompassing public insurance system now also covering the self employed and civil servants. A comparison of the two countries shows that the Austrian system provides much higher benefits. Economic developments in Germany and Austria have been rather close in recent years. This, we argue, shows that a strong public pension insurance does not hamper a country’s economic performance.     

Ageing in Europe

For many people all over Europe, there is an understanding and an expectation that in old age they will be taken care of by the state. High social security contributions throughout the three or four decades of a working life are rationalised by the prospect of a straightforward transition out of the labour force when the time comes. While this was a reasonable expectation in decades past, a number of factors have combined to cause people all across the continent to feel very anxious about what awaits them once it is time to exit the labour force into retirement. The well-documented demographic transition of many rich European countries is a big factor, as greying populations start to weigh on the sparser younger generations, leading to increasing dependency ratios that would cause any social security system to buckle. The Great Recession has not helped matters, and the austerity measures still crippling many vulnerable European nations will not make anyone in these countries feel optimistic about their post-working lives. The following papers look at different threads of the new reality of ageing in Europe, from pension reform and prolonging the working life to more qualitative aspects such as an analysis of the quality of life of the elderly across Europe. They serve to inform and advise on an important issue that will affect everyone in Europe at some point in their lives.     

A random coefficients mixture hidden Markov model for marketing research

The hidden Markov model (HMM) provides a framework to model the time-varying effects of marketing mix variables. When employed in a panel data context, it is important to properly account for unobserved heterogeneity across individuals. We propose a new random coefficients mixture HMM (RCMHMM) that allows for flexible patterns of unobserved heterogeneity in both the state-dependent and transition parameters. The RCMHMM nests all HMMs found in the marketing literature. Results of two simulation studies demonstrate that 1) averaging across a large number of different data generating processes, the RCMHMM outperforms all its nested versions using both in-sample and out-of-sample performance and 2) the RCMHMM is more robust than its nested versions when underlying model assumptions are violated. In addition, we apply the RCMHMM to an empirical application where we examine the effectiveness of in-game promotions in increasing the short-term demand for Major League Baseball (MLB) attendance. We find that the effectiveness of four promotional categories varies over the course of the season and across teams and that the RCMHMM performs best.     

Changes in the stock of on-the-job training,race, and wage growth

This article analyzes the rate of return to on-the-job-training (OJT) investment and in particular, the different rates of return faced by whites and nonwhites. Using data from thePanel Study of Income Dynamics (PSID) on tenure on a particular job and on the amount of time necessary for the average person to become fully trained on that job, I estimate the amount of training (in months) acquired by each individual on each job held. Log wage growth is then regressed on changes in the stock of training the individual held with the current firm. In one specification, changes in the stock of training are interacted with race dummies. The results suggest that the rate of return to an additional month of training is actually higher for nonwhites than for whites.     

Open Entry and Local Telephone Rates: The Economics of IntraLATA Toll Competition

The Telecommunications Act of 1996 removes state-level legal and regulatory barriers to entry that previously have proscribed facilities-based interchange carriers from entering intraLATA toll markets. Traditionally, these markets have provided excess profits that local exchange companies ostensibly have used to subsidize local telephone rates. Elimination of these entry barriers, then, raises concern that the resulting intensification of competition will force unwanted local residential rate increases. In this paper, we critically examine the local-rate-increase question both theoretically and empirically. Our analysis finds no evidence that intraLATA toll competition will adversely affect local rates.     

Firm heterogeneity and aggregate business services exports: Micro evidence from Belgium,France, Germany and Spain

This paper uses detailed micro data on services exports at the firm–destination–service level to analyse the role of firm heterogeneity in shaping aggregate services exports in Belgium, France, Germany and Spain from 2003 to 2007. We decompose the level and the growth of aggregate services exports into different trade margins paying special attention to firm heterogeneity within countries. We find that the weak export growth of France is at least partly due to poor performance by small exporters. By contrast, small exporters are the most dynamic contributors to the aggregate exports of Belgium, Germany and Spain. Our results highlight the importance of firm heterogeneity in understanding aggregate export growth.     

A PORTFOLIO OF THREATS TO AMERICAN AGRICULTURE

This article outlines some of the biggest economic issues threatening the long-term survival of American farming and ranching. In general, the threats are derived from the intersection of global and local scales of decision making. International economic development, personal finance decisions, and political, social, and environmental issues are all part of the portfolio of threats. At the top of the list of threats is the bottom line. Profit margins are being squeezed, causing producers to diversify out of agriculture to earn sufficient returns to enable them to remain in agriculture as long as possible. American policy is expected to allow agriculture to continue shrinking because (1) the sector is losing its comparative advantage, and (2) it may become a deadweight loss to the economy.
