Localized technological change, new information technology and the knowledge-based economy: The European evidence

This work analyzes the co-evolution of new information and communication technologies and the knowledge-intensive business industry. New information technology affects the actual conditions of information, its basic characteristics of appropriation and tradability, favouring the role of business services as forces of interaction between knowledge components in the generation of new technology. Empirical analyses, based on input/output statistics of the European economy in the second half of 1980's, demonstrate the existence of a correlation between the usage of business and communication services and confirm their high output elasticity.     

Restricted Kalman filtering revisited

We propose a more compact and general derivation of results concerning the estimation of linear state space models with linear restrictions in the state vector. The resulting methodological contributions are that the restricted Kalman filtering is valid regardless of the type of linear restriction being considered, and that linear restrictions can be carried out by any type of state smoothing.     

Option-based risk management of a bond portfolio under regime switching interest rates

In the present paper, we assume an economy with regime switching short rates and show how the Value at Risk of a financial position on zero-coupon bonds, hedged by buying protective put options under budget constraints, can be minimized by selecting optimal (regime-dependent) strike prices.     

Forecasting Surrender Rates Using Elliptical Copulas and Financial Variables

A multistage stochastic model to forecast surrender rates for life insurance and pension plans is proposed. Surrender rates are forecasted by means of Monte Carlo simulation after a sequence of GLM, ARMA-GARCH, and copula fitting is executed. The model is illustrated by applying it to age-specific time series of surrender rates derived from pension plans with annuity payments of a Brazilian insurer. In the GLM process, the only macroeconomic variable used as an explanatory variable is the Brazilian real short-term interest rate. The advantage of such a variable is that we can take future market expectation through the current term structure of interest rates. The GLM residuals of each age/gender group are then modeled by ARMA-GARCH processes to generate i.i.d. residuals. The dependence among these residuals is then modeled by multivariate Gaussian and Student's t copulas. To produce a conditional forecast on a stock market index, in our application we used the residuals of an ARMA-GARCH model fitted to the Brazilian stock market index (Ibovespa) returns, which generates one of the marginal distributions used in the dependence modeling through copulas. This strategy is adopted to explain the high and uncommon surrender rates observed during the recent economic crisis. After applying known simulation methods for elliptical copulas, we proceeded backwards to obtain the forecasted distributions of surrender rates by application, in the sequel, of ARMA-GARCH and GLM models. Additionally, our approach produced an algorithm able to simulate multivariate elliptical copulas conditioned on a marginal distribution. Using this algorithm, surrender rates can be simulated conditioned on stock index residuals (in our case, the residuals of the Ibovespa returns), which allows insurers and pension funds to simulate future surrender rates assuming a financial stress scenario with no need to predict the stock market index.     

Localised appropriability: pecuniary externalities in knowledge exploitation

Pecuniary externalities are crucial in shaping the strategies for the valorisation of the distinctive competences and the economic success of innovative firms. The analysis of conditions for localised knowledge appropriation and exploitation makes it possible to identify idiosyncratic production factors. The introduction of directed technological change biased towards their intensive usage provides the opportunity for the exploitation of technological knowledge.     

Keynes and India, 1909–1913: a study on foreign investment policy

Abstract

Keynes's work on India before the First World War concentrated on analysis of the gold exchange standard and the stabilization of the rupee external value. Indian monetary arrangements were framed into a plan for foreign investment, implemented by the India Office in London. This policy, which was a typical example of public control over investments, occasioned Keynes's first job as an applied economist. Although neglected by Keynesian scholarship, this learning by doing experience is likely to have played a significant role in the young economist's training and education.     

Asset pricing with endogenous aspirations

We develop the classical asset pricing analysis assuming that the representative agent is characterized by endogenous aspirations. The agent's aspirations at time t are given by a linear combination of the standard of living (habit) at time t (the "forward" part) and of the conditional expectation at t of the habit at the end of the agent's life (the "backward" part). With this process we capture the fact that the agent's preferences are affected by what he plans to do in the future. Under certain conditions, the risk premium turns out to be higher than that obtained with an additive expected utility when both the forward and the backward parts affect the utility negatively.     

Customer-Driven Product Development Through Quality Function Deployment in the U.S. and Japan

Quality Function Deployment is a tool for bringing the voice of the customer into the product development process from conceptual design through to manufacturing. It begins with a matrix that links customer desires to product engineering requirements, along with competitive benchmarking information, and further matrices can be used to ultimately link this to design of the manufacturing system. Unlike other methods originally developed in the U.S. and transferred to Japan, the QFD methodology was born out of Total Quality Control (TQC) activities in Japan during the 1960s and has been transferred to companies in the U.S. This article reports on the results of a 1995 survey of more than 400 companies in the U.S. and Japan using QFD. The research questions investigated in this study were developed both inductively from QFD case studies in the U.S. and Japan and deductively from the literature. The reported results are in part counterintuitive. The U.S. companies reported a higher degree of usage, management support, cross‐functional involvement, use of QFD driven data sources, and perceived benefits from using QFD. For the most part, the main uses of QFD in the U.S. were restricted to the first matrix (“House of Quality”) that links customer requirements to product engineering requirements and rarely was this carried forward to later matrices. U.S. companies were more apt to use newly collected customer data sources (e.g., focus groups) and methods for analyzing customer requirements. Japanese companies reported using existing product data (e.g., warranty) and a broader set of matrices to a greater extent. The use of analytical techniques in conjunction with QFD (e.g., simulation, design of experiments, regression, mathematical target setting, and analytic hierarchy process) was not wide spread in either country. U.S. companies were more likely to report benefits of QFD in improving cross‐functional integration and better decision‐making processes compared to Japanese companies. Possible reasons for these cross‐national differences as well as their implications are discussed.
