Currency boards,depoliticization and macroeconomic stability: the political economy of institutional complementarities*

This article analyzes the potential for institutional design to depoliticize macroeconomic policy-making by examining currency board arrangements. It develops a novel argument to understand the effects of institutional design based on institutional complementarities. This argument highlights that the functioning of a given institution is conditioned by the broader institutional context. The article contrasts this framework with two common approaches – here termed the institutional design and the epiphenomenalism views – and argues that the centrality of institutional complementarities can account for the mixed record of currency boards. The most important complementarities of a currency board are with fiscal, labor market and informal institutions, which are important prerequisites for successful currency boards. By drawing on recent advances in the study of depoliticization, we show how these institutions contribute to governmental, societal and discursive depoliticization. This argument is evaluated by examining three case studies of currency boards – Argentina, Estonia and Lithuania. The article also explores some broader implications of this analysis for understanding the depoliticization of economic policy.     

Statistical Analysis of Linear Degradation and Failure Time Data with Multiple Failure Modes

The paper considers linear degradation and failure time models with multiple failure modes. Dependence of traumatic failure intensities on the degradation level are included into the models. Estimators of traumatic event cumulative intensities, and of various reliability characteristics are proposed. Prediction of residual reliability characteristics given a degradation value at a given moment is discussed. Non-parametric, semiparametric and parametric estimation methods are given. Theorems on simultaneous asymptotic distribution of random functions characterising degradation and intensities of traumatic events are proposed. Asymptotic properties of unconditional and residual reliability characteristics estimators are given. Real tire wear and failure time data are analysed.
