Increased attention has recently been given to technical efficiency of small-scale irrigation to achieve food security and increase agricultural development. In this paper, the authors classify irrigation supply management methods as cooperative or non-cooperative, introduce social capital by...

We use the data envelopment analysis (DEA) method to estimate the relative efficiency of the current strategy for each player in a game by taking the spatial distribution of strategies as input and the total payoff as output. Based on the optimal value of the DEA model, we present a DEA...

A new type of horizontal axis wind turbine adopting the Archimedes spiral blade is introduced for urban-use. Based on the angular momentum conservation law, the design formula for the blade was derived using a variety of shape factors. The aerodynamic characteristics and performance of the...

Using data for six OECD countries, this paper studies the effect of macroeconomic conditions on the mortality index kt in the well-known Lee-Carter model. Significant correlations are found with real GDP growth rates in Australia, Canada, and the United States, and with unemployment rate changes...

Motivated by a recent demographic study establishing a link between macroeconomic fluctuations and the mortality index kt in the Lee-Carter model, we assess the impact of macroeconomic fluctuations on the solvency of a life insurance company. Liabilities in our stochastic simulation framework...

We exploit the natural experiment of the 2005 income tax reform in Germany to study the effects of tax incentives on consumer behaviour in life insurance markets. Our empirical analysis of sociodemographic, economic and psychological household characteristics elicited in the German SAVE study...

This paper analyzes an individual's post retirement longevity risk management strategy allowing for systematic longevity risk, recent product innovations, and product loadings. A complete-markets discrete state model and multi-period simulations of portfolio strategies are used to assess...
