In social science literature there is a wide range of effectiveness studies for early education and care programmes for young children. But these studies usually distinguish the effects of these programmes without considering their costs. This is where efficiency analysis studies in Economics begin. This article presents three fundamental approaches to efficiency analysis before looking in more detail ...

Research usually finds a positive size-efficiency relationship, but few studies focus on sectors dominated by small and medium-sized firms (SMEs). This paper fills this gap by analyzing this relationship in the German mechanical engineering industry sector, which is both successful and increasingly dominated by SMEs. The analysis, using a large and representative dataset, finds that small and large ...

We estimate a model of intertemporal male labor supply behavior which explicitly accounts for the effect of income taxation and the transfer system. Moreover, we model the demand-side driven rationing risk that prevents agents from choosing the optimal labor supply state. Our results show that elasticities derived in an unconstrained pure choice model are significantly higher compared to a model with ...

In this paper we report the use of the open source Spatiotemporal Epidemiological Modeler (STEM, www.eclipse.org/stem) to compare three basic models for seasonal influenza transmission. The models are designed to test for possible differences between the seasonal transmission of influenza A and B. Model 1 assumes that the seasonality and magnitude of transmission do not vary between influenza A and ...

It is increasingly observable that competitors in different industries share customer data, which can be used for targeted pricing. We propose a modified Hotelling model with two-dimensional consumer heterogeneity to analyze the incentives for such sharing and its ensuing welfare effects. We show that these incentives depend on the type of customer data and on consumer heterogeneity in the strength ...

Two studies investigated the overpowering hypothesis as a possible explanation for the currently inconclusive empirical picture on age differences in affective responding to unpleasant events. The overpowering hypothesis predicts that age differences in affective responding are particularly evident in highly resource-demanding situations that overtax older adults' capacities. In Study 1, we used a ...

Many Colombians are confronted with the ongoing conflict that influences their decision making in everyday life, including their behavior in labor markets. This study focuses on the impact of violent conflict on self-employment, enlarging the usual determinants with a set of conflict variables. Our estimation strategy compares three different estimates: one from fixed-effects panel data (OLS-FE), estimates ...

Many contemporaneously aggregated variables have stochastic aggregation weights. We compare different forecasts for such variables, including univariate forecasts of the aggregate, a multivariate forecast of the aggregate that uses information from the disaggregated components, a forecast which aggregates a multivariate forecast of the disaggregate components and the aggregation weights, and a forecast ...

The paper investigates whether transforming a time series leads to an improvement in forecasting accuracy. The class of transformations that is considered is the Box-Cox power transformation, which applies to series measured on a ratio scale. We propose a nonparametric approach for estimating the optimal transformation parameter based on the frequency domain estimation of the prediction error variance, ...

In order to address carbon leakage and preserve the competitiveness of domestic industries, some industrialized Annex I countries have proposed to implement carbon tariffs. These tariffs would be levied on energy-intensive imports from developing non-Annex I countries that have not agreed to binding emissions reductions. This action could have detrimental welfare impacts, especially on those developing ...
