Turkish Monetary Policy and Components of Aggregate Demand: A VAR Analysis with Sign Restrictions Model

Cataloged from PDF version of article.This article estimates the effects of monetary policy on components of aggregate demand using quarterly data on Turkish economy from 1987-2008 by means of structural Vector Autoregression (VAR) methodology. This study adopts Uhlig's (2005) sign restrictions on the impulse responses of main macroeconomic variables to identify monetary shock. This study finds that expansionary monetary policy stimulates output through consumption and investment in the short-run. However, expansionary monetary policy is ineffective in the long-run

Towards an ergonomic linguistics: Application to the design of controlled natural languages

International audienceThis article proposes to define a "new" discipline within applied linguistics: ergonomic linguistics. The article addresses issues concerning language use within organisations, focusing on human-oriented Controlled Natural Languages (CNLs) whose role is to limit the problems encountered with natural language, in professional contexts in particular. An ergonomic linguistics approach involves first taking into account real linguistic productions and analysing them with corpus linguistics methods, and then evaluating the efficacy of linguists' recommendations using cognitive evaluation or acceptance tests. Two projects concerning human-oriented CNLs that adopt an ergonomic linguistics approach are presented, the first in the space domain and the second in aeronautics

What Does Ex-Post Evidence Tell Us About the Output Effects of Future Tax Reforms?

This paper reviews the existing evidence on the effects of tax reforms on output levels and growth over the short and long run from different strands of the literature. It develops and applies criteria to evaluate the usefulness of ex-post estimates to predict the effects of tax reforms ex-ante. These include whether the estimated policy change can be replicated in practice and whether the estimates are reliable. Based on these criteria we present detailed tables summarizing and comparing ex-post estimates of the effects of tax reforms. Overall, our review suggests that at least the direction of the long-run growth effects can be predicted with a reasonable degree of certainty. However, our review also suggests that depending on the tax change, trade-offs between short-run stabilization and long-run growth may arise and that more research on this question is needed
