An individual's investment in mating or keeping a pair bond intact may be influenced not only by the attractiveness of its current mate, but also by that of other potential mates. In this study, we investigated the effect of relative attractiveness on pair-bond behaviour in bearded reedlings, Panurus biarmicus. We showed that mate attractiveness, in terms of beard length in males and tail lengt...

The influence that grandparents have on the life history traits of their descendants has been studied extensively. However, no attention has been paid to the potential influence a grandparent's own reproductive history has on the investment they make in their grandchildren. We use data from 658 Swiss grandchildren and 591 of their grandparents to investigate whether grandparents' reproductive s...

We offer an investment-based explanation of momentum. The neoclassical theory of investment implies that expected stock returns are related to expected investment returns, defined as the next-period marginal benefits of investment divided by the current-period marginal costs of investment. Empirically, winners have higher expected growth of investment-to-capital and higher expected marginal pro...

This paper provides a theory to analyze the consequences of financing constraints for firm characteristics such as investment, profitability, leverage, the fraction of external equity, the probability of default and the cost of capital. This theory is based on the effects of future investment opportunities and the legal protection of investors on entrepreneurs’ incentives to divert funds to the...

Investment in renewable energies especially solar energies is encountered with numerous uncertainties considering the increased dynamism in economic and financial conditions and makes investment in this field irreversible to a large extent, paying attention to modern methods of economic appraisal of such investments is highly important.

In this paper, an optimal design of the renewable combustion plant has been investigated with the aim of ensuring the required load on the Gorgor station. The purpose of this study is to minimize the cost of the proposed hybrid unit during the period of operation of the designed system simultaneously. Information on the intensity of solar radiation and the intensity of wind blowing in the area ...

We survey recent microeconometric research on investment and employment that has used panel data on individual firms or plants. We focus on model specification and econometric estimation issues, but we also review some of the main empirical findings. We discuss advantages and limitations of microeconomic data in this context. We briefly review the neoclassical theory of the demand for capital a...
