Empirical Evaluation of Fair Use Flat Rate Strategies for Mobile Internet

The fair use flat rate is a promising tariff concept for the mobile telecommunication industry. Similar to classical flat rates it allows unlimited usage at a fixed monthly fee. Contrary to classical flat rates it limits the access speed once a certain usage threshold is exceeded. Due to the current global roll-out of the LTE (Long Term Evolution) technology and the related economic changes for telecommunication providers, the application of fair use flat rates needs a reassessment. We therefore propose a simulation model to evaluate different pricing strategies and their contribution margin impact. The key input element of the model is provided by so-called discrete choice experiments that allow the estimation of customer preferences.     

Determinants of the Choice of Migration Destination*

This paper examines migrants’ choice of destination conditional on migration. The study uses data from two rounds of Nepal Living Standard Surveys and a Population Census and examine how the choice of a migration destination is influenced by various covariates, including income differentials across possible destinations. We find that migrants move primarily to nearby, high population density areas where many people share their language and ethnic background. Better access to amenities is significant as well. Differentials in average income across destination districts are significant in univariate comparisons but not once we control for other covariates. Differentials in consumption expenditures are statistically significant but smaller in magnitude than other determinants. It is differentials in absolute, not relative, consumption between destination districts that are correlated with the destination of work migrants. Except for the latter, results are robust to different specifications and datasets.     

Futures basis,inventory and commodity price volatility: An empirical analysis

We employ a large dataset of physical inventory data on 21 different commodities for the period 1993–2011 to empirically analyze the behavior of commodity prices and their volatility as predicted by the theory of storage. We examine two main issues. First, we analyze the relationship between inventory and the shape of the forward curve. Low (high) inventory is associated with forward curves in backwardation (contango), as the theory of storage predicts. Second, we show that price volatility is a decreasing function of inventory for the majority of commodities in our sample. This effect is more pronounced in backwardated markets. Our findings are robust with respect to alternative inventory measures and over the recent commodity price boom.     

New development: The crisis and European local government reforms

This article highlights the main reform trajectories put in place in French, Italian, German and Portuguese local governments during the recent crisis and identifies a number of important trends: for example increasing centralization of decision-making powers away from local governments. The authors explain why local governments have an opportunity to use reforms during the crisis to strategically reposition their value proposition.     

Attachment orientations in business‐to‐business relationships

Attachment theory has produced an impressive body of evidence for explaining individual differences in personal relationship behavior. The current study examines whether attachment theory can be fruitfully extended to business‐to‐business relationships. Hypotheses about the impact of personal attachment orientations on key relationship constructs are developed and empirically tested in two business‐to‐business relationships. Customers who are securely attached in their personal relationships with their romantic partners experience higher levels of satisfaction, trust, and repurchase intent in their business‐to‐business relationships. In addition, an attachment scale that is specifically tailored for a business‐to‐business context is developed. Two dimensions of business attachment are empirically derived: secure business attachment measures the ability and willingness to rely on the business partner, and close business attachment measures the desire to develop personal bonds with a business partner or its employees. The two business attachment dimensions can be used to segment customers with respect to their intrinsic retainability and their preference for personal bonding with their business partners. © 2009 Wiley Periodicals, Inc.     

Social roles, human capital, and the intrahousehold division of labor: evidence from Pakistan

Using detailed data from rural Pakistan, this paper investigateswhether human capital, learning-by-doing, gender, and familystatus affect the division of labor within households. Resultssuggest the presence of returns to individual specializationin all farm, non-farm, and home based activities. The intrahouseholddivision of labor is influenced by comparative advantage basedon human capital and by long-lasting returns to learning-by-doing,but we also find evidence of a separate effect of gender andfamily status. Households seem to operate as hierarchies withsexually segregated spheres of activity. The head of householdand his or her spouse provide most of the labor within theirrespective spheres of influence; other members work less. Whenpresent in the household, daughters-in-law work systematicallyharder than daughters of comparable age, height, and education.Other findings of interest are that there are increasing returnsto scale in most household chores, that larger households workmore off farm, and that better educated individuals enjoy moreleisure.

Asset Prices and History: The Case of Austria

Historical events are reflected in asset prices. Looking at Austrian government bond prices traded on the Swiss stock exchange during WWII provides therefore a useful way of interpreting the importance the thousands of people directly and indirectly engaged in stock markets attributed to various war events. An econometric analysis of the relationship between government bond values and events in Austrian history reveals that some generally considered crucial events connected with WWII are clearly reflected in Austrian government bond prices. This holds, in particular for the beginning and the end of the war. The annexation of Austria by Germany in 1938 which seemingly looked as being overwhelmingly and passionately welcomed by the Austrian population negatively affected the evaluation of Austrian government bonds, i.e. it was considered to be to the disadvantage of Austria by the people who put their own personal fortune at risk.     

Subjective welfare,isolation, and relative consumption

The recent literature has shown that subjective welfare depends on relative income. Much of the existing evidence comes from developed economies. What remains unclear is whether this is a universal human trait or an artifact of a prosperous, market-oriented lifestyle. Using data from Nepal, a mountainous country where many households still live in relative isolation, we test whether poorer and more isolated households care less about relative consumption. We find that they do not. We investigate possible reasons for this. We reject that it is due to parental concerns regarding the marriage prospects of their children. But we find evidence in support of the reference point hypothesis put forth by psychologists: household heads having migrated out of their birth district still judge the adequacy of their consumption in comparison with households in their district of origin.
