This paper surveys recent theoretical economic research on long term care (LTC). LTC differs from health care: it is about nursing; it is mostly provided by unpaid caregivers (mainly spouses and children), whereas both the market and the State play a modest role. The future of LTC appears to be...

In this paper, we consider a décision-maker facing a financial risk flanked by a background risk, possibly non-financial, such as health or environmental risk. A decision has to be made about the amount of an investment (in the financial dimension) resulting in a future benefit either in the...

Total tourist arrivals are the sum of disaggregate subcomponent arrivals by country of origin. We use seven time-series models to assess whether the aggregate approach that directly forecasts the total tourist arrivals outperforms the disaggregate approach that produces the total arrival...

This paper presents a global approach for museum assessment. We define a museum as an entity which needs to be evaluated according to three well defined tasks: preservation, research and communication, and outcomes. We propose a methodology based on the determination of efficiency frontiers....

In this paper we use data on five social inclusion indicators (poverty, inequality, unemployment, education and health) to assess the performance of 15 European welfare states (EU15) over a ten-year period from 1995 to 2004. Aggregate measures of performance are obtained using index number...

In this paper, we empirically analyze the evolution of firms’ productivity and how the efficiency changes with variations in the inputs’ origin. Using firm-level information on a sample of Irish firms, we assess the importance of the imported inputs’ quota for a firm’s efficiency, as...

Using data from the Community Innovation Survey for Belgium in two consecutive periods, this paper explores the relationship between firm-level innovation activities and the propensity to start exporting. To measure innovation, we include indicators of both innovative effort (R&D activities) as...

The welfare impact of a merger involves the market power offense and the efficiency defense. Salant et al. (1983) show that mergers among symmetric firms are unprofitable except for monopolization. We characterize the limit to this merger paradox in a simple linear Cournot oligopoly with...

The authors examine a variant of the uncapacitated lot-sizing model of Wagner-Within involving sales instead of fixed demands, and lower bounds on stocks. Two extended formulations are presented, as well as a dynamic programming algorithm and a complete description of the convex hull of solutions.
