    Notes: We study an optimal growth model with one-hoss-shay vintage capital, where labor resources can be allocated freely either to production, technology adoption or capital maintenance. Technological progress is partly embodied. Adoption labor increases the level of embodied technical progress. First, we are able to disentangle the amplification-propagation role of maintenance in business fluctuations: in the short run, the response of the model to transitory shocks on total factor productivity in the final good sector are definitely much sharper compared to the counterpart model without maintenance but with the same average depreciation rate. Moreover, the one-hoss shay technology is shown to reinforce this amplification-propagation mechanism. We also find that accelerations in embodied technical progress should be responded by a gradual adoption effort, and capital maintenance should be the preferred instrument in the short run.

    Estimating the Welfare Effects of U.S. Distortions in the Ethanol Market Using a Partial Equilibrium Trade Model (2007)

    Notes: In this paper the impact of distortions on U.S. imports of ethanol from Brazil are calculated. This is achieved by using two-stage least squares to estimate a partial equilibrium trade model based on annual data from 1975 to 2006. From this the derived export supply and import demand elasticities are used to derive "back-of-the-envelope" measures of the static and cumulative deadweight losses, assuming the distortions are not eliminated. The results presented support the hypothesis that the U.S. and Brazil would reap gains from trade if distortions in the U.S. ethanol market were eliminated.

    Strategic Experts and Improvising Regulators: Explaining the IASC's Rise to Global Influence, 1973-2001 (2005)

    Notes: This article traces the ascent of the International Accounting Standards Committee (IASC) from an obscure group with little influence in the early 1970s to a pre-eminent position as global accounting standard-setter in 2001. I argue that the rise of the IASC can be explained by several factors, including the IASC's ability to build legitimacy through technical expertise, to embed itself in a network of international organizations, and to benefit from rivalries among developed and developing countries and among European and American regulators. But the most important reason for the IASC's success is that its core values aligned strongly with the interests of the most powerful regulator--the US Securities and Exchange Commission.

    Learning to Control pH Processes at Multiple Time Scales: Performance Assessment in a Laboratory Plant (2007)

    Notes: This article presents a solution to pH control based on model-free learning control (MFLC). The MFLC technique is proposed because the algorithm gives a general solution for acid-base systems, yet is simple enough for implementation in existing control hardware. MFLC is based on reinforcement learning (RL), which is learning by direct interaction with the environment. The MFLC algorithm is model free and satisfying incremental control, input and output constraints. A novel solution of MFLC using multi-step actions (MSA) is presented: actions on multiple time scales consist of several identical primitive actions. This solves the problem of determining a suitable fixed time scale to select control actions so as to trade off accuracy in control against learning complexity. An application of MFLC to a pH process at laboratory scale is presented, showing that the proposed MFLC learns to control adequately the neutralization process, and maintain the process in the goal band. Also, the MFLC controller smoothly manipulates the control signal.

    The Role of Distance in Gravity Regressions: Is There Really a Missing Globalisation Puzzle? (2007)
    Berkeley, Calif. : Berkeley Electronic Press (now: De Gruyter)

    Notes: The main aim of this paper is to investigate the role of distance in gravity regressions in relation to the missing globalisation puzzle cited by Coe et al. (2002). These authors claimed that the fact that distance coefficients do not fall over time is another puzzle that should have been added in Obsfeld and Rogoff's (2000) paper, in which six major puzzles in international macroeconomics were cited. In order to do so, a linear and a non-linear gravity model are estimated for a cross-section of 65 countries over the period 1980-1999. Non-linear specifications of the gravity model have been recently used in the literature to address the issue of non-declining transport costs over time (Coe et al., 2002 and Croce et al., 2004). However, we claim that there is no missing globalisation puzzle once the linear specification results are correctly interpreted. The main findings are that distance has a different effect for developed and developing countries and that the grounds for using a non-linear specification are not clear since the linear specification, in general terms, shows better performance than the non-linear one.

    An Integrated Analysis of Individual and Aggregated Health Data Using Estimating Equations (2007)

    Notes: Analyses of individual disease-exposure data within a population are useful when exposure of interest varies sufficiently within the population. When the within-population variance of exposure is limited, however, power of the individual-data analysis is reduced. In such situations, aggregated-data analyses of disease data across populations, with a sample of individual exposure data from each population, can be powerful in estimating the exposure effect if between-population variation of exposure is large. In this paper, we consider a new analytical framework that is a combination of the individual- and aggregated-data analyses, based on an estimating equation approach. The proposed analysis utilizes strengths from individual data and aggregated data in the estimation of the exposure effect of interest, depending on which of the exposure variations (within- versus between-population) dominates. Simulation studies under various different scenarios were performed to show the strengths of the proposed approach in the estimation of the exposure effects of interest.
