Libor Market Models versus Swap Market Models for Pricing Interest Rate Derivatives: An Empirical Analysis

We empirically compare Libor and Swap Market Models for thepricing of interest rate derivatives, using panel data on pricesof US caplets and swaptions. A Libor Market Model can directlybe calibrated to observed prices of caplets, whereas a SwapMarket Model is calibrated to a certain set of swaption prices.For both models we analyze how well they price caplets and swaptionsthat were not used for calibration. We show that the Libor MarketModel in general leads to better prediction of derivative pricesthat were not used for calibration than the Swap Market Model.Also, we find that Market Models with a declining volatilityfunction give much better pricing results than a specificationwith a constant volatility function. Finally, we find that modelsthat arechosen to exactly match certain derivative prices areoverfitted; more parsimonious models lead to better predictionsfor derivative prices that were not used for calibration.

Price rigidity and market-clearing: a conceptual clarification

This article tests the view (derived from Hicks and Patinkin)that non-market clearance may be caused by slow adjustment (‘processrigidity’). There are models where market-rationing ispresent and derives from some form of rigidity, but this rigiditycannot be considered as process rigidity. It is similarly possibleto accommodate the idea of process rigidity within the Marshallianresearch programme. What is missing is that market-rationingmight be its corollary. The reason such a causal link is oftenbelieved to exist lies in a generic use of the concept of rigidity,used to designate alternative and incompatible phenomena: ‘exogenousend-state rigidity’ and ‘equilibrium end-state rigidity’,as well as process rigidity. It is true that these first twoforms of rigidity create market rationing. The belief that slowadjustment also generates market rationing results from theunwarranted extension to process rigidity of conclusions whichare only valid for the first two.     

Competition,transmission and bank pricing policies: Evidence from Belgian loan and deposit markets

This paper addresses the pass-through from market interest rates to retail bank interest rates. The paper advocates a heterogeneous approach and applies it to the Belgian banking market. A substantial proportion of the heterogeneity in bank pricing policies can be explained by the bank lending channel and the relative market power hypothesis. The results also suggest that the long-term pass-through is typically less than one-for-one, rejecting the completeness hypothesis. While there is no convincing evidence for asymmetry in retail rates, large deviations from equilibrium mark-ups are faster reduced than small deviations. Overall, conditions for corporate loans are more competitive compared to consumer loans. Demand and savings deposits have, by far, the most rigid prices.     

The Wage Elasticity of Labour Supply: A Synthesis of Empirical Estimates

Summary This paper performs a meta-analysis of empirical estimates of uncompensated labour supply elasticities. For the Netherlands, we find that an elasticity of 0.5 for women and 0.1 for men is a good reflection of what the literature reveals. The elasticity for men hardly differs between countries, but for women some cross-country variation is found. The increasing participation rate of women may lead to a somewhat lower elasticity in the future. Both the specification of the hours function and the estimation method are found to affect elasticity estimates.

Macroeconomic Consequences of Outsourcing: An Analysis of Growth, Welfare, and Product Variety

Outsourcing of non-core activities is nowadays a common business strategy. Declining transaction and transportation costs caused by the advent of Information and Communication Technology are a potentially important driving force behind this development. This paper provides a theoretical framework for analysing a firm's incentive to follow such a strategy of outsourcing and its consequences for macroeconomic variables like growth and product variety. We divide production activities into core and non-core activities. Non-core activities can be performed within the firm or can be mediated by the market. We derive conditions under which outsourcing occurs, and under which outsourcing is socially desirable. These conditions do not necessarily coincide. Outsourcing may hence be a profitable strategy for firms, while it is socially suboptimal. Crucial parameters in the model are the relative scale of core versus non-core activities, management costs, transaction costs and love for variety of consumers.

The Italian Banking Structure in the 1990s: Testing the Multimarket Contact Hypothesis

The multimarket contact hypothesis holds that more contacts between firms competing in the same markets may induce more collusion. This paper tests the hypothesis for the Italian banking market, analysing the behaviour of the largest Italian banks from 1990 to 1996. Market rivalry is gauged by changes in loan market shares and interest rates in each Italian province. We estimate the effects of increasing multimarket contacts, concentration indicators, banks' costs and loan demand on variations in market shares and interest rates. No support is found for the multimarket contact hypothesis. Geographical overlap in banking is positively correlated with changes in market shares, confirming the thesis of an overall increase in competition within the Italian banking system. Greater multimarket links also seem to correspond to lower lending rates.
