News shocks and asset price volatility in general equilibrium

We study equity price volatility in general equilibrium with news shocks about future productivity and monetary policy. As West (1988) shows, in a partial equilibrium present discounted value model, news about the future cash flow reduces asset price volatility. We show that introducing news shocks in a canonical dynamic stochastic general equilibrium model may not reduce asset price volatility under plausible parameter assumptions. This is because, in general equilibrium, the asset cash flow itself may be affected by the introduction of news shocks. In addition, we show that neglecting to account for policy news shocks (e.g., policy announcements) can potentially bias empirical estimates of the impact of monetary policy shocks on asset prices.     

Inflation and output volatility under asymmetric incomplete information

The assumption of asymmetric and incomplete information in a standard New Keynesian model creates strong incentives for monetary policy transparency. We assume that the central bank has better information about its objectives than the private sector, and that the private sector has better information about shocks than the central bank. Transparency has the potential to trigger a virtuous circle in which all agents find it easier to make inferences and the economy is better stabilised. Our analysis improves upon existing work by endogenising the volatility of both output and inflation. Improved transparency most likely manifests itself in falling output volatility.

Real rigidities, productivity improvements and investment dynamics

The theoretical literature on business cycles predicts a positive investment response to productivity improvements, a prediction we question from theoretical and empirical perspectives. We show that a short-term negative response of investment to a positive technology shock is consistent with a reasonably parameterized new Keynesian dynamic stochastic general equilibrium (DSGE) model in which firm-specific capital introduces an additional real rigidity, and monetary policy is not fully accommodative. Employing Bayesian techniques, we provide evidence that permanent productivity improvements have short-term, contractionary effects on investment. Although this result can be obtained from both firm-specific and rental capital models, only in the case of the former is the average price duration in line with the microeconometric evidence.     

Gender and management on Spanish SMEs: an empirical analysis

Few studies have investigated the presence of women on the boards of directors of companies. Those that have been done have focused on large firms. In this study we analyzed the gender diversity of a sample of Spanish small and medium enterprises. These firms are of great importance in terms of their number, the employment they provide, and their sales. Furthermore, there is an open debate in Spain about gender equality after the passing of several laws against gender discrimination. We found that women's presence on boards generates a negative impact on firm performance and this result may be due to less risky strategies implemented by women directors. This finding is interesting because it sheds light on how women can affect the functioning of a board. We also found that family firms and firms with a financial institution as the main shareholder tend to have more women on the board. Finally, we show that firms with less debt, more assets, and larger boards have more women as directors.     

The effect of transaction costs, payment terms and power on the level of raw materials inventories

This paper proposes and tests an explanation for the level of raw materials inventories based on transaction cost economics theory and the role of power in a supply chain. According to this explanation, raw materials inventories are larger the higher a company's transaction costs and the lower its storage-related production and management costs. Factors that affect these costs are the company's vulnerability to opportunism, whether the input becomes more or less costly to store and manage as it moves through the supply chain, payment terms and the company's power in relation to its supplier. This explanation for the level of raw materials inventories was tested on a large sample of customer industries matched to their main supplier industries. Consistent with this theory, the empirical results show that companies hold larger raw materials inventories the more money their suppliers spend on research and development and the less important the customers are to their suppliers. These results are important because they indicate companies must consider a wider range of factors than previously thought necessary when establishing inventory policy.

Exchange rate dynamics and their effect on macroeconomic volatility in selected CEE countries

To understand the potential for forming an optimum currency area it is important to investigate the origins of macroeconomic volatility. We focus on the contribution of real exchange rate shocks to macroeconomic volatility in selected Central and Eastern European countries. The contribution of real exchange rate shocks relative to other shocks allows us to evaluate whether the real exchange rate is a source of volatility or a buffer against shocks, as the theory suggests. The identification of the contributions is based on variance decomposition in two-country structural VAR models, which are identified by the sign restriction method. For most of the countries in the sample, shocks are predominantly symmetric relative to their effective counterpart, although the role of non-symmetric shocks is non-negligible. In general, for all the countries considered except Bulgaria and Slovenia, the real exchange rate does not generate large volatility over the business cycle and, with the exception of Bulgaria and Romania, is mostly driven by the non-symmetric shocks. These results are consistent with the real exchange rate having a shock-absorbing nature.     

Cost and Production Duality: The Case of the Regulated Firm

This paper examines a generalization of cost-production duality for regulated firms. It derives an equivalency between the production function and conditional factor demands for the case where the firm's optimization problem is subject to a set of additional (regulatory) constraints. This procedure is extended to an optimization problem within a dynamic framework which leads to the recovery of the firm's technology.     

CONTRACTS,ENTREPRENEURS, MARKET CREATION AND JUDGEMENT: THE CONTEMPORARY MAINSTREAM THEORY OF THE FIRM IN PERSPECTIVE

This survey gives an overview of the theory of the firm as it is formulated within the contemporary ‘mainstream’ of economics. Two groupings of theories are briefly discussed: principal–agent and incomplete contract models. Next, three of the most recent contributions regarding firms are considered. The reference point approach is looked at first followed by a discussion of Spulber's book The Theory of the Firm. Last, we consider the entrepreneurial judgement perspective.     

THE ‘REFERENCE POINT’ APPROACH TO THE THEORY OF THE FIRM: AN INTRODUCTION

There is a small but growing literature on the ‘reference point’ approach to incomplete contracts as formulated by Hart and Moore. The reference point approach has begun to be applied to the theory of the firm in 3 recent papers. This introduction reviews the main theoretical aspects of each of these papers. It then discusses the relationship between the reference point approach to the firm, the transaction cost approach and the property rights approach. Here it is argued that the reference point approach is a step back towards ex post inefficiencies, away from reliance on ex ante inefficiencies.     

Cointegration, causality and the transmission of shocks across wheat market in Pakistan

This paper uses quarterly price data and examines the transmission of shocks across different spatially separated locations besides identifying causality among these locations. Johansen and Juselius’s (Econ. Stat., 52, 160–210, 1990) multivariate cointegration procedure identified two cointegrating vectors among these locations. Following Toda and Yamamoto (J. Econom., 66, 225–250, 1995), causality tests showed only one bi-directional causality and it was between Peshawar and Hyderabad locations. Faisalabad and Sargodha appeared independent (i.e. exogenous) market locations in price discovery process. Peshawar market showed maximum (i.e. 5) number of significant links. The generalized impulse response functions, though, suggested similar (cyclical) pattern of responses across the markets, but their time profile, which provides insight into the system’s speed of convergence to long run equilibrium path, varied with different level of extent and persistency. Responses to shock originating in consumption markets (i.e. Karachi, Peshawar and Lahore) remained short lived; whereas the shocks stemming from surplus wheat producing locations (i.e Multan, Sargodha and Faisalabad) produced long and more persistent responses.      

Bond risk, bond return volatility, and the term structure of interest rates

This paper explores the time variation in the bond risk, as measured by the covariation of bond returns with stock returns and consumption growth, and in the volatility of bond returns. A robust stylized fact in empirical finance is that the spread between the yields on long- and short-term bonds forecasts future excess returns on bonds at varying horizons positively; in addition, the short-term nominal interest rate forecasts both the stock return volatility and the exchange rate volatility positively. This paper presents evidence that movements in both the short-term nominal interest rate and the yield spread are positively related to changes in the subsequent realized bond risk and bond return volatility. The yield spread appears to proxy for business conditions, while the short rate appears to proxy for inflation and economic uncertainty. A decomposition of bond betas into a real cash flow risk component and a discount rate risk component shows that yield spreads have offsetting effects in each component. A widening yield spread is correlated with a reduced cash-flow (or inflationary) risk for bonds, but it is also correlated with a larger discount rate risk for bonds. The short rate only forecasts the discount rate component of the bond beta.

A global study of graduate management of technology programs

In the last decade, the field of technology management has attracted considerable attention from practitioners and scholars. The rapid emergence of powerful and innovative technologies in manufacturing, computing, telecommunications and the life sciences, such as biotechnology are making the strategic management of technology, a critical task in virtually all organizations. Reflecting this trend, several universities offer graduate programs in the management of technology (MOT). These programs have originated from various academic schools and disciplines (business, engineering, public policy) creating considerable diversity of focus, themes emphasized, courses, and student backgrounds. The rise of these programs, in part, reflects the growing need for managers and technologists who are able to understand, contribute to, and manage a wide variety of technology-based programs and organizations. This paper presents the results of a global study of graduate MOT programs. Over fifty (50) universities participated in the research reported in this paper. Findings related to research trends, curriculum developments, staffing, program implementation, and program emphases are examined. Several recommendations are advanced for universities considering initiating or further developing their MOT program. In addition, observations about the future direction of the field are made.

HRM professionals and their perceptions of HRM and firm performance in the Philippines

This paper reports the findings of a study conducted in the Philippines that examines the extent of adoption of human capital-enhancing human resource (HR) and industrial relations (IR) practices. Differences between locally owned and other organizations in these practices and their relationship to firm performance were also investigated. Questionnaire responses were obtained from managers and union representatives from 128 organizations located in the Philippines. The results indicated that there was, on average, a fairly high level of adoption of practices consistent with a strategic approach to human resource management (HRM), with foreign-owned firms tending to show a slightly higher level of adoption of such practices. A scale representing the adoption of a more conciliatory and union-friendly IR approach was found to be a significant predictor of perceived firm performance. Surprisingly, the level of strategic integration between HRM and business planning and most human capital-enhancing HR practices were not significant predictors of perceived firm performance. Research and practical implications in relation to the role of HRM in enhancing firm performance are discussed.     

Technological proximity and the choice of cooperation partner

This paper provides empirical tests of hypotheses of cooperative behavior provided by evolutionary approaches in the resource-based view of the firm. The influences of “technological proximity”, individual incentives to cooperate and managerial tools to the choice of research partner are analyzed. Using German patent data we can show the positive influence of those three determinants. The results of this paper confirm theories dealing with the path-dependency of research activities.
