Islamic Economics in the Late Ottoman Empire: Menâpirzâde Nuri Bey's Mebâhis-i İlm-i Servet

The existing literature on Islamic economics suggests that Islamic economics is a twentieth-century phenomenon with its roots in medieval Islamic intellectual and theological history, thereby leaving a centuries-long gap in the history of Islamic economic thinking. This study aims at taking a first step towards filling this gap by examining a nineteenth-century example of Islamic economics in late Ottoman economic literature. Suggesting a broader definition of Islamic economics, this article investigates a prominent Ottoman intellectual's efforts to define, reveal, and revive a tradition of Islamic economics in historical and intellectual context.     

THE STANDARD OF LIVING IN THE UNITED STATES

A common approach to the evaluation of the standard of living is based on a function of real income. In the United States this often takes the form of CPI-deflated mean household income. Material well-being is more appropriately evaluated using a consumption-based index. Using data from the Consumer Expenditure Surveys we find that real mean income provides an inaccurate representation of the level and trend of the standard of living relative to real per equivalent total expenditure in the postwar United States. The differences between real income and real total expenditure per household equivalent member are found at all levels of aggregation.     

The venture capital entry model on game options with jump-diffusion process

This paper aims to apply game options to construct the optimal decision-making and management tool for venture capital (VC) firms. This model emphasizes the inferences with game options on the market structures formed by different competition and investment strategies of the two VC firms to reflect the investment returns. These market structures are classified into an entry-deterred game (specific monopoly), a leader's dominated strategies (duopoly), and simultaneous investment. It is considered how to select investment timing to avoid any potential competitive threats in order to provide the optimal expected threshold values for the investment decisions of VC firms.     

An optimization approach to business buyer choice sets: How many suppliers should be included?

In many new or repeat purchasing situations, business buyers must decide how many suppliers to consider (a “choice set”) in determining which supplier(s) to actually buy from or contract with. This paper develops an optimization approach to determining the size of the choice set, taking into consideration buyer utility and search and evaluation costs. A theoretical model is developed for both one-time and repeat purchase situations. The model is estimated using empirical data received from bids received for procurement auctions. In these auctions, suppliers provide bids for steel pipe based on two product attributes (price and delivery time). Model sensitivity to small changes in parameters is also tested.     

The relation between national cultural dimensions and tax evasion

Although penalties and audits exist, tax evasion is a widespread phenomenon and continues to be a problem for many countries. National culture may contribute to a further understanding of intentional noncompliance across countries. In this study, we investigate the influence of national culture on tax compliance levels across 50 countries. Using Hofstede's (1980) cultural framework as a basis for our hypotheses, we find that a noncompliant country's profile is characterized by high uncertainty avoidance, low individualism, low masculinity, and high power distance. Our results have implications for both research and practice. This is the first study to employ Hofstede's cultural framework as an explanator of international tax compliance diversity and serves as the starting point for the development of an international tax compliance framework. Tax policy implications also are addressed.
