Private consumption,public consumption and liquidity constraints in developing countries: some empirical evidence

This paper extends the empirical work of Giovannini (1983, 1985) in seeking to identify the elasticity of substitution in consumption in developing countries using the Euler equation approach. Allowing for liquidity constraints in capital markets which force a percentage of aggregate consumption growth to track income growth to track income growth, we report static and time-varying estimates of this percentage and the elasticity of intertemporal substitution, as well as estimates of substitution between private and public consumption and implied utility function parameters. Our results suggest that liquidity constraints are a pervasive feature of developing country consumption data and that the elasticity of intertemporal substitution is near-zero for the majority of countries considered.     

Management regimes in science-based innovation: control and uncertainty during early phases of new drug development

The international pharmaceutical industry is facing a challenge in terms of being able to deliver new and innovative drugs at lower cost. During the last 10 years, a range of new scientific procedures and technologies has been introduced into the industry, partially derived from the advancement of genomics research. However, to date, few have resulted in new registered drugs. In addition to the new technologies, various managerial techniques and methods have been introduced with the intention of increasing the transparency of operations. This paper reports on a study of how scientists during the early phases of new drug development conceive of this present management regime emphasising quantitative output. Thinking of new drug development as an intellectual pursuit in order to understand the elementary mechanisms of the biological organisms on the molecular level, scientists call for an understanding and adjustment of the managerial techniques structuring this work, accompanied by ambiguities and uncertainty.     

Contributions of the Galbraith “Technostructure” to the Growing Crisis of the U.S. Economy

This paper lays the methodological foundations of an analytical framework that may help shed some new light on the issue of territorial inequalities in the digital economy. It opposes the recent tendency to build up an evolutionary economic geography as an alternative not only to the so-called "New Economic Geography" (namely "geographical mainstream economics") but also to the institutional economic geography. The paper advocates the development of an evolutionary and institutional approach in economic geography, which would be meso-focused. Finally, it presents some insights that highlight the heuristic potential of this approach in reappraising the territorial features of the digital economy.     

Farm household efficiency in Bangladesh: a comparison of stochastic frontier and DEA methods

This study compares estimates of technical efficiency obtained from the stochastic frontier approach and the Data Envelopment Analysis (DEA) approach using farm-level survey data for rice farmers in Bangladesh. Technical inefficiency effects are modelled as a function of farm-specific socioeconomic factors, environmental factors and irrigation infrastructure. The results from both the approaches indicate that efficiency is significantly influenced by the factors measuring environmental degradation and irrigation infrastructure.     

On the predictive power of monetary exchange rate model: the case of the Malaysian ringgit/US dollar rate

Despite anecdotal and survey evidence suggesting the presence of discrimination against customers in stores, restaurants and other small-transaction consumer markets, few studies exist that identify or quantify the nature of any unequal treatment. We provide evidence from a field study of wait times in Boston-area coffee shops that suggests that female customers wait an average of 20 seconds longer for their orders than do male customers even when controlling for gender differences in orders. We find that this differential in wait times is inverse to the proportion of employees who are female and directly related to how busy the coffee shop is at the time of the order. This supports the conclusion that the observed differential is driven at least in part by employee animus and/or statistical discrimination rather than unobserved heterogeneity in the purchasing behaviour of female customers.     

Why is TFP growth sectorally concentrated?

Research shows that total factor productivity (TFP) growth is weak in European countries. This is inter alia attributed to the fact that substantial TFP growth is limited to a few industries. Because TFP growth is typically understood as technological progress, it is concluded that technology diffusion between sectors in Europe is hampered. We use EU KLEMS data sets to decompose sectoral TFP for nine European countries by means of a Malmquist approach in order to identify potential sources besides technical progress. Applying Harberger diagrams, we describe the sectoral distribution of TFP growth, efficiency gains and losses, economies of scale and technological progress. The analysis reveals that technological progress is quite evenly distributed across sectors in most European countries. The wide scattering of TFP growth is explained by deviating efficiency developments and the unused economies of scale. We conclude that the technology transfer between sectors in most European countries seems to work. Therefore, Europe in general does not need a new technology policy, but a further integration of the markets and a reduction of national market entry barriers. This requires further unification of pan-European standards in fields like trade and crafts codes or consumer protection policies.     

Analyzing determinants of bond yield spreads with Bayesian Model Averaging

This paper analyzes determinants of country default risk in emerging markets, reflected by sovereign yield spreads. The results reported so far in the literature are heterogeneous with respect to significant explanatory variables. This could indicate a high degree of uncertainty about the “true” regression model. We use Bayesian Model Averaging as the model selection method in order to find the variables which are most likely to determine credit risk. We document that total debt, history of recent default, currency depreciation, and growth rate of foreign currency reserves as well as market sentiments are the key drivers of yield spreads.     

Externalities of public firm presence: Evidence from private firms' investment decisions

Public firms provide a large amount of information through their disclosures. In addition, information intermediaries publicly analyze, discuss, and disseminate these disclosures. Thus, greater public firm presence in an industry should reduce uncertainty in that industry. Following the theoretical prediction of investment under uncertainty, we hypothesize and find that private firms are more responsive to their investment opportunities when they operate in industries with greater public firm presence. Further, we find that the effect of public firm presence is greater in industries with better information quality and in industries characterized by a greater degree of investment irreversibility. Our results suggest that public firms generate positive externalities by reducing industry uncertainty and facilitating more efficient private firm investment.     

Banking deregulation and innovation

We document empirical support for a key micro-level channel—innovation by young, private firms—through which financial sector deregulation affects economic growth. We find that intrastate banking deregulation, which increased the local market power of banks, decreased the level and risk of innovation by young, private firms. In contrast, interstate banking deregulation, which decreased the local market power of banks, increased the level and risk of innovation by young, private firms. These contrasting effects on innovation also translated into contrasting effects on economic growth. Our study suggests that the nature of financial sector deregulation crucially affects its potential benefits to the real economy.     

Reputational contagion and optimal regulatory forbearance

Existing studies suggest that systemic crises may arise because banks either hold correlated assets, or are connected by interbank lending. This paper shows that common regulation is also a conduit for interbank contagion. One bank's failure may undermine confidence in the banking regulator's competence, and, hence, in other banks chartered by the same regulator. As a result, depositors withdraw funds from otherwise unconnected banks. The optimal regulatory response to this behavior can be privately to exhibit forbearance to a failing bank. We show that regulatory transparency improves confidence ex ante but impedes regulators' ability to stem panics ex post.
