Technology Shocks


Book Description

Understanding the joint dynamics of internat. prices and quantities remains a central issue in internat. bus. cycles. Internat. relative prices appreciate when domestic consumption and output increase more than their foreign counterparts. In addition, both trade flows and trade prices display sizable volatility. This paper incorporates Hicks-neutral and investment-specific TS into a standard two-country general equilibrium model with variable capacity utilization and weak wealth effects on labor supply. Investment-specific TS introduce a source of fluctuations in absorption similar to taste shocks, thus reconciling theory and data. Also presents implications for the transmission mechanism of TS across countries. Illus. This is a print on demand pub.










Investment Specific Technology Shocks and Emerging Market Business Cycle Dynamics


Book Description

This article explores the role of investment specific technology shocks for emerging market business cycle fluctuations. The analysis is motivated by two key empirical facts; the presence of investment specific technical change in the post-war US economy together with the importance of investment goods for the emerging market imports. The goal of this paper is to quantify the contribution of the investment specific technical change in the US for the business cycles of an emerging country in the context of a two country, two sector international real business cycle framework with investment and consumption goods sectors. We estimate the model for Mexico and US data and find that a permanent US originating investment specific technology shock is very important in explaining the Mexican output and investment dynamics. This shock explains around 80% of the investment variability and it accounts for the around 45% of the output variability. We argue that the model's ability to account for the important business cycle features of the data is dependent on the presence of shocks that capture financial frictions as well as a permanent investment specific technology shock that originates in the US.




Technology shocks : novel implications for international business cycles


Book Description

Understanding the joint dynamics of international prices and quantities remains a central issue in international business cycles. International relative prices appreciate when domestic consumption and output increase more than their foreign counterparts. In addition, both trade flows and trade prices display sizable volatility. This paper incorporates Hicks-neutral and investment-specific technology shocks into a standard two-country general equilibrium model with variable capacity utilization and weak wealth effects on labor supply. Investment-specific technology shocks introduce a source of fluctuations in absorption similar to taste shocks, thus reconciling theory and data. The paper also presents implications for the transmission mechanism of technology shocks across countries and for the Barro and King (1984) critique of investment shocks.




Technology Shocks and Aggregate Fluctuations


Book Description

Our answer: Not so well. We reached that conclusion after reviewing recent research on the role of technology as a source of economic fluctuations. The bulk of the evidence suggests a limited role for aggregate technology shocks, pointing instead to demand factors as the main force behind the strong positive comovement between output and labor input measures.




Hysteresis and Business Cycles


Book Description

Traditionally, economic growth and business cycles have been treated independently. However, the dependence of GDP levels on its history of shocks, what economists refer to as “hysteresis,” argues for unifying the analysis of growth and cycles. In this paper, we review the recent empirical and theoretical literature that motivate this paradigm shift. The renewed interest in hysteresis has been sparked by the persistence of the Global Financial Crisis and fears of a slow recovery from the Covid-19 crisis. The findings of the recent literature have far-reaching conceptual and policy implications. In recessions, monetary and fiscal policies need to be more active to avoid the permanent scars of a downturn. And in good times, running a high-pressure economy could have permanent positive effects.




Business Cycles


Book Description

This title provides an overview of the modern theory and empirics of business cycles. The book examines the notion of a business cycle and discusses alternative approaches to modelling. It also discusses what lies ahead for modern business cycle theory.







Cointegrated TFP Processes and International Business Cycles


Book Description

A puzzle in international macroeconomics is that observed real exchange rates are highly volatile. Standard international real business cycle (IRBC) models cannot reproduce this fact. We show that TFP processes for the U.S. and the "rest of the world," is characterized by a vector error correction (VECM) and that adding cointegrated technology shocks to the standard IRBC model helps explaining the observed high real exchange rate volatility. Also we show that the observed increase of the real exchange rate volatility with respect to output in the last 20 year can be explained by changes in the parameter of the VECM.
