A short history of global inequality: The past two centuries

Using social tables, we make an estimate of global inequality (inequality among world citizens) in early 19th century. We then show that the level and composition of global inequality have changed over the last two centuries. The level has increased reaching a high plateau around 1950s, and the main determinants of global inequality have become differences in mean country incomes rather than inequalities within nations. The inequality extraction ratio (the percentage of total inequality that was extracted by global elites) has remained surprisingly stable, at around 70% of the maximum global Gini, during the last 100 years.     

Russian Roller Coaster: Expenditure Inequality and Instability in Russia, 1994–98

This paper uses the second phase of the Russian Longitudinal Monitoring Survey to investigate the changes in expenditure inequality and instability in Russia between the autumn of 1994 and the autumn of 1998. The expenditure distribution is stable in spite of the economic and political turmoil Russia is going through. However, that does not imply much stability. Households experienced considerable fluctuations in their expenditure, with over 60 percent of the population's expenditure either more than doubling or falling to less than half their previous levels. Only about 6 percent of all households experienced an expenditure shock of less than 10 percent. The inquiry in expenditure mobility suggests high levels of transitory variation in the expenditure and high levels of instability.     

Ownership Dynamics with Multiple Insiders: The Case of REITs

We study ownership dynamics of multiple strategic risk-averse insiders facing a moral hazard problem. We show that, when insiders cannot commit,  ex ante , to an ownership policy, the aggregate insider stake gradually declines toward the competitive market allocation. Both the speed of adjustment and the long-term equilibrium aggregate insider ownership level are greater for companies with a larger number of insiders,  ceteris paribus . Using data from U.S. real estate investment trusts, we then test the model and find that the predictions of the model are verified empirically.     

Monetary policy in a small open economy with fixed exchange rate: The case of Macedonia

This paper empirically applies the New Keynesian model for monetary policy analysis in a small open economy with a fixed exchange rate. Official reserves are included in the interest rate rule to account for the constraint that these impose on monetary policy when the exchange rate is fixed. Also, the foreign interest rate is included in order to reflect the necessity of following the foreign monetary policy. The model is applied to Macedonian data from the period 1997 to 2011. In general, results indicate that monetary policy has been focused on domestic objectives during this period, despite the fixed currency. In addition, there seem to have been significant differences in the conduct of the monetary policy in the first and second half of this period. The response to inflation has been more aggressive in the earlier period, at a time when reserves appear less important, while the output gap is found to be important only in the latter period, possibly due to the stronger monetary policy transmission. Finally, results indicate that the monetary policy has likely moved from adaptive in the first period to rational in the second period.     

Value Creation and Value Capture Alignment in Business Model Innovation: A Process View on Outcome-Based Business Models

Industrial manufacturers are innovating their business models by shifting from selling products to selling outcome-based services, where the provider (manufacturer) guarantees to deliver the performance outcomes of the products and services. This form of business model innovation requires a profound yet little understood shift in how value is created, delivered, and captured. To address this research gap, our study examines two successful and four unsuccessful cases of this shift. We find that effectiveness in business model innovation hinges on the three process phases that unfold in collaboration with the customers: value proposition definition, value provision design, and value-in-use delivery. We also find that that success is determined by the alignment of specific value creation and value capture activities in each phase: identifying value creation opportunities—agreeing on value distribution in value proposition definition, designing the value offering—deciding on the profit formula in the value provision design, and finally refining value creation processes—regulating incentive structures in the value-in-use delivery. Our process model contributes to the literature and practice on business model innovation by providing a thorough understanding of how alignment of value creation and value capture processes is ensured, whilst paying special attention to their interdependence and the interactions between provider and customer.

Context-Sensitive Access Control Model for Government Services

During the past two decades, e-government information systems have become less paper-based and more computer-based. Those information systems usually take the form of workflow systems. Due to the large social impact of e-government systems, computer security plays a pivotal role in ensuring its efficiency and effectiveness. Access control is one of the key aspects of computer security. Current access control models do not take into account the context of the system and its environment. In this article, we argue that a formal context-sensitive access control model can improve the development of e-government workflow systems and present a particular context-sensitive access control model. The subject of the article is a specification of the context-sensitive access control model for business processes (COBAC). By using a context-sensitive access control, it is possible to define more sophisticated access control policies that cannot be implemented by existing access control models. The COBAC's context is modeled using Web Ontology Language (OWL) in order to provide formal representation of context, rich representation of diverse contextual information, semantic interoperability between various context-aware systems, and a high degree of inference making. The presented model is applicable in different e-government systems, and supports the definition of access control policies for both simple and complex business processes. The model's prototype is verified by a case study on a real e-government business process—the national petty offense trial proceedings.     

Social costs of public service obligation routes—calculating subsidies of regional flights in Norway

In this note we describe an iterative procedure of how to estimate unit costs per leg of a public service obligation (PSO) route network if certain data is publicly available. The aim of this approach is to make judgments in benchmarking and in regulation if revenues, costs and profits (or losses) per flight and its distribution among these route networks are typical compared to carriers serving networks under a competitive regime. Particularly this note aims to set a reference for the question, if market or bargaining powers are abused and to which extent. This work is thus especially important for PSO cases where a particular network cannot be operated in a profitable manner; therefore, its routes are offered to monopoly providers in a bidding competition and (in most cases) the service needs to be publicly subsidized. We shall apply the procedure on origin-destination matrices from tender documents published by the Norwegian Ministry of Transport and Communications. The Ministry covers incurred losses produced by the bidding and winning carrier. As a first result we can observe that the PSO allocations show indications of an inefficient allocation process reflected in more than three-fold quoted costs on PSO routes above estimated market levels.     

Fixed capital cost,depreciation multiplier and the rate of interest

Suppose in an economy with zero interest rate five new trucks are bought and afterwards the fleet is renewed by investing the annual depreciation quotas. The service life of a truck is four years. What will be the stationary size of the fleet? The assumed answer is four trucks. The correct answer is eight trucks. The difference is measured by a coefficient called depreciation multiplier. The value of the depreciation multiplier is examined for three typical time profiles of fixed assets, and its limits are found to be 1 ?μ?2. It is then shown how the rate of interest can be interpreted as a rate of growth in an economy with unchanged technology. If the rate of interest is made equal to the rate of growth of the economy, the ratio of discounted values of brand new fixed assets and fixed assets of balanced age-distribution is equal to the ratio between gross and net capital in the growing economy with no interest rate.
