Investment in organizational capital

Organizational capital is a specific form of capital that firms accumulate. It relates to the development of codes, technical languages, practical arrangements about how the work is done and to the creation of an organizational culture. The distinctive feature of this form of capital is the fact that it does not contribute directly to an output result. Instead, it can be thought as creating the correct environment for the human factor to maximize its capability of generating value, that is, organizational capital works as an external effect on the accumulation of the human capital input. Nevertheless, organizational capital is a form of capital and therefore it has an investment process associated with it. The paper considers the process of investment in this form of capital and recognizes that it introduces important changes over the firm's profit maximization problem. The problem gains new features relating to its dynamic nature and a condition that guarantees saddle‐path stability can be derived. Copyright © 2007 John Wiley & Sons, Ltd.     

Asset prices and business cycles with costly external finance

This paper asks whether the asset pricing fluctuations induced by the presence of costly external finance are empirically plausible. To accomplish this, we incorporate costly external finance into a dynamic stochastic general equilibrium model and explore its implications for the properties of the returns on key financial assets, such as stocks, bonds and risky loans. We find that the mean and volatility of the equity premium, although small, are significantly higher than those in comparable adjustment cost models. However, we also show that these results require a procyclical financing premium, a property that seems at odds with the data.     

Exponential discounting bias

We address intertemporal utility maximization under a general discount function that nests the exponential discounting and the quasi-hyperbolic discounting cases as particular specifications. Under the suggested framework, the representative agent adopts, at some initial date, an optimal behavior that shapes her consumption trajectory over time. This agent desires to take a constant discount rate to approach the optimization problem, but bounded rationality, under the form of a present bias, deviates the individual from the intended goal. As a result, decreasing impatience will end up dominating the agent’s behavior. The individual will not be aware of her own time inconsistency and, therefore, she will not revise her plans as time elapses, what makes the problem relatively simple to address from a computational point of view. The general discounting framework is used to approach a standard optimal growth model in discrete time. Transitional dynamics and stability properties of the corresponding dynamic setup are studied. An extension of the standard utility maximization model to the case of habit persistence is also considered.     

Sovereign credit ratings and financial markets linkages: Application to European data

We use EU sovereign bond yield and CDS spreads daily data to carry out an event study analysis on the reaction of government yield spreads before and after announcements from rating agencies (Standard & Poor’s, Moody’s, Fitch). Our results show significant responses of government bond yield spreads to changes in rating notations and outlook, particularly in the case of negative announcements. Announcements are not anticipated at 1–2 months horizon but there is bi-directional causality between ratings and spreads within 1–2 weeks; spillover effects especially among EMU countries and from lower rated countries to higher rated countries; and persistence effects for recently downgraded countries.     

Longevity risk, retirement savings, and financial innovation

Over the last couple of decades unprecedented increases in life expectancy have raised important concerns for retirement savings. We solve a life-cycle model with longevity risk, which can be hedged through endogenous saving and retirement decisions. We investigate the benefits of financial assets designed to hedge the shocks to survival probabilities. When longevity risk is calibrated to match forward-looking projections, those benefits are substantial. This lends support to the idea that such hedging should be pursued by defined benefit pension plans on behalf of their beneficiaries. Finally, we draw implications for optimal security design.     

Profits and Fractal Properties: Notes on Marx,Countertendencies and Simulation Models

There are new reasons for revisiting Marx’s elaboration on the rate of profit because contemporary debates provide findings from the MEGA Project, long-term data on the rate of profit, and tools for dealing with complexity and non-equilibrium systems. This article proposes that the interplay between the tendency and the countertendencies of the rate of profit to fall can be translated into a simple system of equations, one based on each chapter of Section Three of Capital—as if Marx sought to mathematically formalise his insights. This article reviews previous debates, presents data and runs a simulation model, showing that the rate of profit behaves as fractals.     

Physical distribution service: A fundamental marketing concept?

This article contends that current discussion and research into the role of physical distribution service in the marketing mix are hampered by a lack of consistent definition of the concept of physical distribution service and its component dimensions. In order to clarify this concept, prerequisites for a theoretically meaningful understanding of physical distribution service are presented and supported by an integrative literature review. The implications of this undertaking are also discussed.     

Optimal Diversification: Reconciling Theory and Evidence

In this paper we show that the main empirical findings about firm diversification and performance are consistent with the maximization of shareholder value. In our model, diversification allows a firm to explore better productive opportunities while taking advantage of synergies. By explicitly linking the diversification strategies of the firm to differences in size and productivity, our model provides a natural laboratory to investigate several aspects of the relationship between diversification and performance. Specifically, we show that our model can rationalize the evidence on the diversification discount ( Lang and Stulz (1994) ) and the documented relation between diversification and productivity ( Schoar (2002) ).     

Joined-up Government of utilities: a meta-review on a public–public partnership and inter-municipal cooperation in the water and wastewater industries

Private-sector participation in public services delivery has been criticized due to unfulfilled expectations. In response, joined-up government is being introduced as an alternative approach to providing water and wastewater services. This approach involves the establishment of horizontal (i.e. inter-municipal cooperation) and vertical (i.e. public–public partnership) integration. Drawing on a meta-review focused on the water and wastewater industries, this study shows that both arrangements have positive aspects, such as cost savings. However, contractual schemes and inter-departmental coordination efforts must be carefully managed or they will fail. In addition, research on cooperation between public bodies is scarce and must be better coordinated concerning study aims and methods.     

Wagner’s Law and Fiscal Illusion: An analysis of state government finances in Brazil

The aim of this article is to analyze state‐level public finances in Brazil. We examine the dynamics of governmental spending in a panel of 26 Brazilian states in search of evidence of Wagner’s Law and Fiscal Illusion Hypothesis. For the period ranging from 2002 to 2015, three methodologies are applied: dynamic ordinary least squares (DOLS), fully modified ordinary least squares (FMOLS), and pooled mean group (PMG). The main empirical results found indicate that (1) there is strong evidence of Fiscal Illusion caused by public deficit and by central government transfer grants; (2) there are possible Flypaper Effects; (3) there is no evidence in support of Wagner’s Law; (4) there is low publicness degree of local expenditures; (5) due to Fiscal Illusion, less‐developed Brazilian states tend to be stuck in a public expenditure growth mechanism, especially in expenses related to non‐public goods, which tend to benefit private interests and lobby groups.
