Sentinels are a conspicuous feature of some cooperative societies and are often assumed to provide benefits in terms of increased predator detection. Similar to other cooperative behaviours, variation in investment in sentinel behaviour should reflect variation in the benefits of such behaviour. However, evidence for this is inconclusive: to date experiments have manipulated the cost of sentine...

In Taiwan stock market, it has been accumulated large amounts of time series stock data and successful investment strategies. The stock price, which is impacted by various factors, is the result of buyer-seller investment strategies. Since the stock price reflects numerous factors, its pattern can be described as the strategies of investors. In this paper, pattern recognition concept is adapted...

Researchers often refer to investment habitats/categories to explain the patterns of comovement in asset returns that cannot be fully clarified by fundamentals. Many factors determine these habitats including investor preferences to size, industry, price-levels and risk-levels. This paper investigates a unique method to explore investment habitat based on the search behavior of investors on the...

Moving workloads on to cloud, promises to be an attractive investment for enterprises planning for a sustainable IT landscape. However, leveraging the existing IT investment of an organization and moving them over to the cloud environment with minimum business disruption and costs, seems to be the biggest challenge in adopting cloud based modernization. Enterprise workloads move into cloud deli...

We develop a tractable two-country overlapping generations model and show analytically that the cross-country differences in financial development help explain three recent empirical facts characterizing international capital flows: financial capital flows from relatively poor to relatively rich countries while FDI flows in the opposite direction; net capital flows are from poor to rich countri...

Ever since the start of the Industrial Revolution in Britain in the 1760s, innovation and investment have been crucial elements in economic explanations of the dynamics of capitalism. Classical economics recognises that innovation embodied in the form of new machines through fixed capital investment is the essential process for realising economic development. This study sets up a theoretical li...

In this paper I examine the intracultural variability of parental and alloparental caregiving among the Aka foragers of the Central African Republic. It has been suggested that maternal kin offer higher frequencies of allocare than paternal kin and that maternal investment in infants will decrease when alloparental assistance is provided. Behavioral observations were conducted on 15 eight- to t...

This paper studies theoretically how the cross-country differences in the institutional quality (IQ) of the domestic credit markets shape the patterns of international capital flows when such IQ differences cause productivity differences across countries. IQ affects productivity by changing productivity-agency cost trade-offs across heterogeneous investment projects, which have opposite effects...

Characterizations of coy females and ardent males are rooted in models of sexual selection that are increasingly outdated. Evolutionary feedbacks can strongly influence the sex roles and subsequent patterns of sex differentiated investment in mating effort, with a key component being the adult sex ratio (ASR). Using data from eight Makushi communities of southern Guyana, characterized by varyin...

AK growth models predict that permanent changes in government policies affecting investment rates should lead to permanent changes in a country’s GDP growth. Charles Jones (1995) sees no evidence for this prediction in data for 15 OECD countries after World War II: rates of investment, especially for equipment, have risen while GDP growth rates have not. This article provides evidence supportin...
