A productivity analysis of Central and Eastern European banking taking into account risk decomposition and environmental variables

This paper develops a Luenberger productivity index that is applied to a technology where desirable and undesirable outputs are jointly produced and are possibly negative. The components of this Luenberger productivity index - the efficiency change and the components of the technological shift - are then decomposed into factors determined by the technology, adjusted and then for ‘risk and environment’, ‘risk management’ and ‘environmental effects’. The method is applied to Central and Eastern European banks operating during 1998-2003 utilising three alternative input/output methodologies (intermediation, production and profit/revenue). Additionally, the comparative analysis of the sensitivity of the productivity indices in the choice of the methodologies is undertaken using statistical and kernel density tests. It is found that the main driver of productivity change in Central and Eastern European banks is technological improvement. That is, in the beginning of the analysed period, the results hinged on the banks ability to capitalise on advanced technology and successfully take into account ‘risk and environmental’ factors. Whereas, in later periods, one of the most important factors of technological improvement/decline was ‘risk management’. Finally, the tests employed confirm previous findings, such as Pasiouras (2008)in this journal, that different input/output methodologies produce statistically different productivity results. Finally, we find that external factors, such as ‘risk in the economy’ and banking production, and a ‘corruption perception’ affect the productivity of banks.     

Inventories and optimal monetary policy in a small open economy

We study how inventory investment affects the design of optimal monetary policy in a New Keynesian small open economy model. We find that under producer currency pricing, when the intratemporal elasticity of substitution is smaller than 1, optimal monetary policy in our model with inventories is similar to a standard model without inventories. However, when the intratemporal elasticity of substitution is larger than 1, inventory investment increases the importance of nominal exchange rate stabilization relative to a standard model without inventories. The importance of nominal exchange rate stabilization increases with the intratemporal elasticity of substitution.     

Funded pensions and intergenerational and international risk sharing in general equilibrium

We explore intergenerational and international risk sharing in a general equilibrium multiple-country model with two-tier pensions systems. The exact design of the pension system is key for the way in which risks are shared over generations. The laissez-faire market solution fails to provide an optimal allocation because the young cannot share in the financial risks. However, the existence of wage-indexed bonds combined with a pension system with a fully funded second tier that pays defined wage-indexed benefits can reproduce the first best. If wage-indexed bonds are not available, mimicking the first best is not possible, except under special circumstances. We also explore whether national pension funds want to deviate from the first best by increasing domestic equity holdings. With wage-indexed bonds this incentive is absent, while there is indeed such an incentive when wage-indexed bonds do not exist.     

Can Commercialization Improve the Performance of Stock Exchanges Even without Corporatization?

We examine the performance of mutual, demutualized, and publicly listed exchanges and find evidence of improved performance along the exchange governance continuum, with publicly traded exchanges exhibiting better operating performance than demutualized exchanges. However, our robustness test, focusing on the corporatized exchanges that have gone through the three phases of the governance structure, shows that the listed exchanges do not exhibit evidence of incremental gains in efficiency and profitability beyond what they achieved at the demutualization phase. We conclude that commercialization provides sufficient freedom for exchanges to exploit monopoly rents before going public, while corporatization brings about proper valuation of the exchanges’ franchise.

Venture Capital and Other Private Equity: a Survey

We review the theory and evidence on venture capital (VC) and other private equity: why professional private equity exists, what private equity managers do with their portfolio companies, what returns they earn, who earns more and why, what determines the design of contracts signed between (i) private equity managers and their portfolio companies and (ii) private equity managers and their investors (limited partners), and how/whether these contractual designs affect outcomes. Findings highlight the importance of private ownership, and information asymmetry and illiquidity associated with it, as a key explanatory factor of what makes private equity different from other asset classes.
