A duality theory of payment systems

We model the Central Bank’s management of intraday liquidity in modern real-time gross settlement systems as a linear programming problem parameterized by different intraday monetary policies, such as reserve requirements, net debit caps and Lombard loans. We then use duality theory to determine the shadow-prices of constraints of each bank. These shadow-prices can be used by the Central Bank to set personalized intraday monetary policies in order to reduce idleness of money and to give a microfoundation of the too-big-to-fail policy.     

Continuous utility functions in consumer theory: A set of duality theorems

The aim of this paper is to characterize, in terms of primitives, the class of expenditure functions and the class of indirect utility functions that are associated with the class of continuous utility functions. Once the duality results are established, the theory is extended by theorems which provide useful methods for identifying these classes of expenditure and indirect utility functions.     

Efficient and optimal programs when investment is irreversible: A duality theory

An attempt is made in this paper to formulate a satisfactory duality theory of efficient and optimal programs in intertemporal models with irreversible inveatment. The introduction of the constraint that depreciated capital stock cannot be used for present consumption makes the meaningful choice and interpretation of dual variables a more difficult problem, as is pointed out by means of an example. A new definition of a competitive program is introduced, and this is seen to lead to useful characterizations of efficient and optimal programs.     

Axiomatic characterizations of the duality correspondence in consumer theory

In this paper we present several axiomatic characterizations of the mapping assigning to the utility function of a consumer its associated indirect utility function as well as characterizations of the inverse correspondence. Some of them refer to the standard case of real-valued functions, while others involve functions taking values in an arbitrary complete chain. In this abstract framework, we also give some simultaneos characterizations of both transformations.     

The coalitional approach to core theory

The Core-Walras Equivalence is examined in a finite or infinite economy in which the competitive gap is bounded by the size of the atoms in the economy. The economy is represented by a Boolean algebra of coalitions, and coalitions rather than individual agents are taken as a primitive concept. Coalition arbitrage plays the central role in our analysis.     

The theory of corporate takeover bids: A subgame perfect approach

In this paper I re-examine Grossman & Hart's (1980a) earlier work on corporate takeovers and address three main shortcomings of their theory. First, their theory implies that in the ‘Nash equilibrium’ either all shareholders will decide to tender their shares or all will refuse the raider's tender offer. Hence, they look only at the pure strategy equilibria. Second, there does not exist any free-rider problem in the extreme cases of pure strategy equilbria because everyone sells his or her share and the raider does not have to deal with any minority shareholder in the equilibrium. On the other hand, if the raid fails and no one sells, then there is no question of dilution either. I show some mixed-strategy equilibria using assumptions of Grossman and Hart. Third, Grossman and Hart claim that their theory rules out the possibilities of takeovers by the inefficient raider in which the shareholders who tender their shares are worse off than they would have been otherwise with the incumbent management. It appears from the model that their argument is based on rather arbitrary assumptions.     

The opportunity cost of duality

A dual representation of a technology, e.g., a cost function, may not contain all of the technological information, but it will contain all of the information about input vectors that would be chosen by a cost-minimizing firm. At least this much is clear for deterministic technologies. The main question addressed in this paper is whether the same can be said about stochastic technologies and their dual representations. Despite some pessimism expressed in the stochastic frontier literature on this question, we argue that there is no extra cost imposed in the stochastic case. Thus, the conclusion of this paper is: Just dual it!     

The cyclical nature of markups in Canadian manufacturing: A production theory approach

In this paper the effects of cost and demand characteristics on the magnitude and cyclical behaviour of markups in Canadian manufacturing are measured within a production theory framework. Price to marginal cost ratios for various manufacturing industries are computed, and the impact art their secular and cyclical trends from changes in capacity utilization, scale economies, variable input prices, import competition, unemployment and other exogenous market and technological determinants are explored using adjusted markup indexes and elasticities. The measured price margins seem weakly procyclical. Further, evaluation of the determinants of these cycles suggests that the procyclical nature of markups is primarily related to exogenous factors affecting costs such as energy price ‘shocks’, and that cost characteristics underlying scale economies provide a countercyclical influence that counteracts the profitability arising from markups.     

The relationship between private investors and small firms: an agency theory approach

Many small firms in Sweden are characterized by a lack of equity capital. For several years measures to increase the equity capital have been discussed. In this discussion the private investors' market has received virtually no attention. This study presents some preliminary results of the private investors in Sweden.

The research in small firms financing is characterized by a lack of theoretical framework. One basic assumption in the study is that agency theory can provide an essential framework to explain the interaction between the private investor and entrepreneur. Twenty-five hypotheses generated from agency theory are formulated and tested on 62 small unlisted firms in Sweden. Multiple regression analysis is used for the causal analyses.

The empirical results in the study show inter alia that the geographic distance and the private investor's knowledge about the portfolio firm's transformation process seem to be the most influential factors for determining the private investor's involvement in the portfolio firms. It is also interesting to notice that none of the variables, frequency of contacts and the private investor's operational work in the portfolio firm affect the performance of the firm. Contrary to conventional wisdom, private investors do not add value to their portfolio firms through their interaction with the entrepreneurs.

The theoretical conclusion is that agency theory does not provide any satisfactory framework to explain the private investor - entrepreneur relationship. Some of the basic assumptions in agency theory seem to be invalid. A model for the relationship between private investors and entrepreneurs is developed in which four interaction strategies are identified. The model gives implications on two levels: the portfolio level and the individual case level.     

The duality of bankruptcy process in Finland

Standard bankruptcy prediction methods lead to models weighted by the types of failure firms included in the estimation sample. These kinds of weighted models may lead to severe classification errors when they are applied to such types of failing (and non-failing) firms which are in the minority in the estimation sample (frequency effect). The purpose of this study is to present a bankruptcy prediction method based on identifying two different failure types, i.e. the solidity and liquidity bankruptcy firms, to avoid the frequency effect. Both of the types are depicted by a theoretical gambler's ruin model of its own to yield an approximation of failure probability separately for both types. These models are applied to the data of randomly selected Finnish bankrupt and non-bankrupt firms. A logistic regression model based on a set of financial variables is used as a benchmark model. Empirical results show that the resulting heavily solidity-weighted logistic model may lead to severe errors in classifying non-bankrupt firms. The present approach will avoid these kinds of error by separately evaluating the probability of the solidity and liquidity bankruptcy; the firm is not classified bankrupt as long as neither of the probabilities exceeds the critical value. This leads the present prediction method slightly to outperform the logistic model in the overall classification accuracy.     

The Moses-Predöhl pull and the neoclassical location theory : An alternative approach

This paper shows that the appearance of the controversial Moses-Prednhl pull is due to the two-stage approach (the separation of the production decision and the location decision) which has been applied in the neoclassical location theory. It also shows the Moses-Prednhl pull is zero by using the well-known envelope theorem in the two-stage approach. Furthermore, it provides an alternative approach to show the Moses-Prednhl pull is zero by considering the production decison and the location decision simultaneously.

Property appraisal in high-rises: A cooperative game theory approach

The construction of the higher stories in a building is utterly contingent upon the construction of the lower ones, while the construction of lower stories does not require the construction of the higher ones. This rationale underlies our adoption of a cooperative game theory methodology for examining the value of units based on the cost approach of land appraisal. Particularly, we propose the Shapley value solution to examine the allocation of the land and construction cost among the stories of the building. We explore the allocation mechanism and derive several closed-form properties by which the value pattern of stories in a building is rationalized. The proposed cost allocation may, among other things, generate values when comparable market prices are unobservable (consistent with the cost approach); may be used by courts in order to compute compensations in cases of disputes regarding expansions and redevelopments of existing structures among co-owners; and may determine the rent cost allocation in an organization with several profit centers located on different floors of a building.     

Property rights theory,transaction costs theory,and agency theory: an organizational economics approach to strategic management

Property rights theory has common antecedents with contractual theories of the firm such as transaction costs and agency theories, and is yet distinct from these theories. We illustrate fundamental theoretical principles derived from these three theories by analyzing the business case of oil field unitization. Theoretical principles and application of theory to oil field unitization are each summarized. From this, it is possible to see how property rights theory is well suited to explain business situations where inefficient economic outcomes persist. Additionally, property rights theory forges new theoretical connections with other branches of organizational economics, in particular, resource‐based theory.

Reflections on developments in institutional theory: Toward a relational approach

In this review article, we reflect upon recent developments in institutional theory with particular emphasis on first, how organizational fields have been conceived and second, on how action has been conceptualized and incorporated into institutional accounts. We show that progress has been made in regard to our understanding of field level processes and the role of institutional actors. However, we also identify a number of weaknesses and challenges, which we assess in the context of developing a relational approach to institutional analysis.     

Production theory,uncertain prices and investment portfolios

This paper examines the allocative decisions of a competitive firm where input and output prices are uncertain and where the capital asset pricing model prevails. The firm behaves much as a profit maximizer under certainty, except that certainty equivalent prices formally replace the known prices. These certainty equivalent prices are composed of the expected price, the covariance of the price with the market (a measure of systematic risk) and a measure of risk aversion in the economy. Both static and comparative static propositions emerge in a natural way as extensions of standard, competitive and profit maximizing behavior. In addition, the model contains both the certainty case and the risk-neutral case as limiting examples.     

Mapping walkability. A subjective value theory approach

The analysis of urban walkability has been extensively explored in the last decades. Despite this growing attention, there is a lack of studies attentive on how citizens' values, individual abilities and urban environment favour or hinder the propensity to walk. Hence, there is a need to explore how preferences and values of citizens vary in space in order to design walkability policies able to improve the capability set of citizens. In this perspective, the design of spatial decision tools aimed to plann public policies for the development of walkable cities needs further investigation. We propose a Multiple Criteria Decision Analysis (MCDA) method aimed to elaborate walkability decision maps for different groups of citizens that reflect their capability to walk in the urban environment. We tested the method in the city of Alghero (Italy). First, we analysed walkability under a normative model named CAWS; then we made a survey with 358 participants in order to study the driving values that influence their choice to walk and finalised to build an evaluation model attentive to individual differences. Cluster analysis was employed to group citizens into 11 groups based on their sociodemographic characteristics and preferences on spatial criteria of walkability. Finally, by integrating GIS with MCDA we built a set of decision maps representative of the walkability of the 11 groups of citizens. Results highlight the importance of citizens’ values for policy design, allow the interpersonal comparison among individuals and group preferences and give new suggestions for the formulation of walkability oriented urban policies. Moreover, the results confirm the usability of the general method as a decision support tool supporting the design of urban policies.     

The challenge of international human resource management: balancing the duality of strategy and practice

Over the last two decades there has been an unprecedented increase in the number of organizations that have internationalized their operations. The international movement of labour that has been concomitant with such expansion of international business has meant that issues associated with the management of human resources across international borders are increasingly important to international human resource managers and academics. The research presented in this paper examines international human resource management (IHRM) pedagogy and practice in Australia. It reports IHRM academicians' and practitioners' understanding of the major issues for teaching and practice in IHRM and elucidates current developments and directions for this field.
