Optimal Monetary Policy with Durable Consumption Goods and Factor Demand Linkages

This paper deals with the implications of factor demand linkages for monetary policy design. We develop a dynamic general equilibrium model with two sectors that produce durable and non-durable goods, respectively. Part of the output produced in each sector is used as an intermediate input of production in both sectors, according to an input-output matrix calibrated on the US economy. As shown in a number of recent contributions, this roundabout technology allows us to reconcile standard two-sector New Keynesian models with the empirical evidence showing co-movement between durable and non-durable spending in response to a monetary policy shock. A main result of our monetary policy analysis is that strategic complementarities generated by factor demand linkages amplify social welfare loss. As the degree of interconnection between sectors increases, the cost of misperceiving the correct production technology of each sector can rise substantially. In addition, the transmission of different sources of exogenous perturbation is altered, compared to what is commonly observed in standard two-sector models without factor demand linkages. In this respect, the role of the relative price of non-durable goods is crucial, as this does not only influence the user cost of durables through the conventional demand channel, but also affects in opposite directions the real marginal cost of production in either sector through the intermediate input channel.input-output interactions, durable goods, optimal monetary policy

Speculation in the oil market

The run-up in oil prices after 2004 coincided with a growing flow of investment to commodity markets and an increased price comovement between different commodities. We analyze whether speculation in the oil market played a key role in driving this salient empirical pattern. We identify oil shocks from a large dataset using a factor-augmented autoregressive (FAVAR) model. We analyze the role of speculation in comparison to supply and demand forces as drivers of oil prices. The main results are as follows: (i) While global demand shocks account for the largest share of oil price fluctuations, financial speculative demand shocks are the second most important driver. (ii) The comovement between oil prices and the price of other commodities is explained by global demand and financial speculative demand shocks. (iii) The increase in oil prices in the last decade is mainly explained by the strength of global demand. However, financial speculation played a significant role in the oil price increase between 2004 and 2008, and its subsequent collapse. Our results support the view that the financialization process of commodity markets explains part of the recent increase in oil prices.Petroleum products - Prices ; Vector autoregression ; Speculation

Optimal Monetary Policy with Durable Consumption Goods and Factor Demand Linkages

This paper deals with the implications of factor demand linkages for monetary policy design. We consider a dynamic general equilibrium model with two sectors that produce durable and non-durable goods, respectively. Part of the output of each sector serves as a production input in both sectors, in accordance with a realistic input-output structure. Strategic complementarities induced by factor demand linkages significantly alter the transmission of exogenous shocks and amplify the loss of social welfare under optimal monetary policy, compared to what is observed in standard two-sector models. The distinction between value added and gross output that naturally arises in this context is of key importance to explore the welfare properties of the model economy. A flexible inflation targeting regime is close to optimal only if the central bank balances inflation and value added variability. Otherwise, targeting gross output variability entails a substantial increase in the loss of welfare.Input-Output Interactions, Durable Goods, Optimal Monetary Policy

Factor demand linkages, technology shocks and the business cycle

This paper argues that factor demand linkages can be important for the transmission of both sectoral and aggregate shocks. We show this using a panel of highly disaggregated manufacturing sectors together with sectoral structural VARs. When sectoral interactions are explicitly accounted for, a contemporaneous technology shock to all manufacturing sectors implies a positive response in both output and hours at the aggregate level. Otherwise there is a negative correlation, as in much of the existing literature. Furthermore, we find that technology shocks are important drivers of business cycle.

Inflation dynamics and real marginal costs: new evidence from U.S. manufacturing industries.

This paper deals with the analysis of price-setting in U.S. manufacturing industries. Recent studies have heavily criticized the ability of the New Keynesian Phillips curve (NKPC) to fit aggregate inflation [see, e.g., Rudd and Whelan, 2006, Can Rational Expectations Sticky-Price Models Explain Inflation Dynamics?, American Economic Review, vol. 96(1), pp. 303-320 ]. We challenge this evidence, showing that forward-looking behavior as implied by the New Keynesian model of price-setting is widely supported at the sectoral level. In fact, current and expected future values of the income share of intermediate goods emerge as an effective driver of inflation dynamics. Unlike alternative proxies for the forcing variable, the cost of intermediate goods presents dynamic properties in line with the predictions of the New Keynesian theory.

Factor demand linkages and the business cycle: interpreting aggregate fluctuations as sectoral fluctuations

This paper investigates the drivers of industry and aggregate fluctuations. We model the dynamics of a panel of highly disaggregated manufacturing sectors. This allows us to consider directly the linkages between sectors typical of any production system, in a framework where the sectors are fully heterogeneous. We establish that these features are fundamental for the propagation of the shocks in the aggregate economy. Aggregate fluctuations can be accounted for by small industry specific shocks. Moreover, a contemporaneous technology shock to all sectors in the economy, i.e. an aggregate technology shock, implies a positive response in both output and hours at the aggregate level. When this intersectoral channel is neglected we find a negative correlation as with much of the literature. This suggests that the standard technology driven Real Business Cycle paradigm is a reasonable approximation of a more complicated model featuring heterogeneously interconnected sectors.Sectors, Technology shocks, Business cycles, Long-run restrictions, Cross Sectional Dependence.

Aggregate fluctuations and the cross-sectional dynamics of firm growth.

This paper argues that important insights into the business cycle can be obtained by exploring the micro-structure of macroeconomic fluctuations. We fit firm-level growth data with the Asymmetric Exponential Power density, which accounts for asymmetric dispersion and kurtosis on either side of the modal rate. Three novel results are reported. First, firms in the left side of the distribution, that is firms that are growing more slowly or declining, are typically more responsive to aggregate shocks than those in the right side of the distribution. Second, trending behavior in the volatility of firm growth is predominantly driven by increasing dispersion in the growth of highly performing .rms. Last, we deliver evidence in support of the view that shifts in the probability mass on either side of the mode may act as important propagators of business fluctuations. The analysis points to .financial frictions as one of the mechanisms capable of inducing non-linear micro adjustment consistent with both aggregate and cross-sectional dynamics.

The Financial Integration of the European Union: Common and Idiosyncratic Drivers

The purpose of this paper is to establish how far the process of financial integration has gone in the European Union. There is growing evidence that the appearance of the Euro has accelerated the integration of a number of financial markets among those countries who have adopted the Euro. We identify the growth in financial integration as the process by which idiosyncratic factors at the national level become less and less important for the behaviour of particular markets. While the Euro plays an important part because it eliminates currency risk, financial integration will still emerge between other European countries as long as the institutional and legal barriers are removed.

Speculation in the oil market

The run-up in oil prices since 2004 coincided with growing investment in commodity markets and increased price co-movement among different commodities. We assess whether speculation in the oil market played a role in driving this salient empirical pattern. We identify oil shocks from a large dataset using a dynamic factor model. This method is motivated by the fact that a small-scale vector autoregression is not informationally sufficient to identify the shocks. The main results are as follows. (i) While global demand shocks account for the largest share of oil price fluctuations, speculative shocks are the second most important driver. (ii) The increase in oil prices over the last decade is mainly driven by the strength of global demand. However, speculation played a significant role in the oil price increase between 2004 and 2008 and its subsequent collapse. (iii) The co-movement between oil prices and the prices of other commodities is mainly explained by global demand shocks. Our results support the view that the recent oil price increase is mainly driven by the strength of global demand but that the financialization process of commodity markets also played a role
