The Dynamic Effects of U.S. Monetary Policy on State Unemployment

This paper studies the transmission of monetary shocks to state unemployment rates, within a novel structural factor-augmented VAR framework with a timevarying propagation mechanism. We find evidence of large heterogeneity over time in the responses of state unemployment rates to monetary policy shocks, which do not necessarily comply with the response of the national unemployment rate. We also find evidence of heterogeneity over the spatial dimension, although geographical proximity seems to play an important role in the transmission of monetary shocks.regional unemployment, structural VAR, factor model, monetary policy

The regional employment impacts of renewable energy expenditures: The case for modelling

One aspect of the case for policy support for renewable energy developments is the wider economic benefits that are expected to be generated. Within Scotland, as with other regions of the UK, there is a focus on encouraging domesticallyâ€based renewable technologies. In this paper, we use a regional computable general equilibrium framework to model the impact on the Scottish economy of expenditures relating to marine energy installations. The results illustrate the potential for (considerable) ‘legacy’ effects after expenditures cease. In identifying the specific sectoral expenditures with the largest impact on (lifetime) regional employment, this approach offers important policy guidance.Renewable energy policy; regional economic impacts; computable general equilibrium modelling.

On Regional Unemployment: An Empirical Examination of the Determinants of Geographical Differentials in the UK

This paper considers the determinants of regional disparities in unemployment rates for the UK regions at NUTS-II level. We use a mixture panel data model to describe unemployment differentials between heterogeneous groups of regions. The results indicate the existence of two clusters of regions in the UK economy, characterised by high and low unemployment rates respectively. A major source of heterogeneity seems to be caused by the varying (between the two clusters) effect of the share of employment in the services sector, and we trace its origin to the fact that the “high unemployment” cluster is characterised by a higher degree of urbanization.distribution dynamics, regional labour markets, unemployment differentials

A Comparison of Results From MRIO and Interregional Computable General Equilibrium (CGE) Analyses of the Impacts of a Positive Demand Shock on the ‘CO2 Trade Balance’ Between Scotland and the Rest of the UK

In previous work we have applied the environmental multi-region input-output (MRIO) method proposed by Turner et al (2007) to examine the ‘CO2 trade balance’ between Scotland and the Rest of the UK. In McGregor et al (2008) we construct an interregional economy-environment input-output (IO) and social accounting matrix (SAM) framework that allows us to investigate methods of attributing responsibility for pollution generation in the UK at the regional level. This facilitates analysis of the nature and significance of environmental spillovers and the existence of an environmental ‘trade balance’ between regions. While the existence of significant data problems mean that the quantitative results of this study should be regarded as provisional, we argue that the use of such a framework allows us to begin to consider questions such as the extent to which a devolved authority like the Scottish Parliament can and should be responsible for contributing to national targets for reductions in emissions levels (e.g. the UK commitment to the Kyoto Protocol) when it is limited in the way it can control emissions, particularly with respect to changes in demand elsewhere in the UK. However, while such analysis is useful in terms of accounting for pollution flows in the single time period that the accounts relate to, it is limited when the focus is on modelling the impacts of any marginal change in activity. This is because a conventional demand-driven IO model assumes an entirely passive supply-side in the economy (i.e. all supply is infinitely elastic) and is further restricted by the assumption of universal Leontief (fixed proportions) technology implied by the use of the A and multiplier matrices. In this paper we argue that where analysis of marginal changes in activity is required, a more flexible interregional computable general equilibrium approach that models behavioural relationships in a more realistic and theory-consistent manner, is more appropriate and informative.To illustrate our analysis, we compare the results of introducing a positive demand stimulus in the UK economy using both IO and CGE interregional models of Scotland and the rest of the UK. In the case of the latter, we demonstrate how more theory consistent modelling of both demand and supply side behaviour at the regional and national levels affect model results, including the impact on the interregional CO2 ‘trade balance’.CGE modelling, MRIO, CO2 trade balance, environmental responsibility

The added value from adopting a CGE approach to analyse changes in environmental trade balances

The application of multi-region environmental input-output (IO) analysis to the problem of accounting for emissions generation (and/or resource use) under different accounting principles has become increasingly common in the ecological and environmental economics literature in particular, with applications at the international and interregional subnational level. However, while environmental IO analysis is invaluable in accounting for pollution flows in the single time period that the accounts relate to, it is limited when the focus is on modelling the impacts of any marginal change in activity. This is because a conventional demand-driven IO model assumes an entirely passive supply-side in the economy (i.e. all supply is infinitely elastic) and is further restricted by the assumption of universal Leontief (fixed proportions) technology implied by the use of the A and multiplier matrices. Where analysis of marginal changes in activity is required, extension from an IO accounting framework to a more flexible interregional computable general equilibrium (CGE) approach, where behavioural relationships can be modelled in a more realistic and theory-consistent manner, is appropriate. Our argument is illustrated by comparing the results of introducing a positive demand stimulus in the UK economy using IO and CGE interregional models of Scotland and the rest of the UK. In the case of the latter, we demonstrate how more theory consistent modelling of both demand and supply side behaviour at the regional and national levels effect model results, including the impact on the interregional CO2 ‘trade balance’.modelling, MRIO, CO2 trade balance, environmental responsibility

The national impact of regional policy : demand-side policy simulation with labour market constraints in a two-region computable general equilibrium model

UK governments generally advocate regional policy as a means of reducing regional disparities and stimulating national growth. However, there is limited comprehension regarding the effects of regional policy on non-target economies. This paper examines the system-wide effects on the Scottish and rest of UK (RUK) economies of an increase in Scottish traded sector exports to the rest of the world. The research is carried out in an inter-regional Computable General Equilibrium framework of the Scottish and RUK economies, under alternative hypotheses regarding wage determination and inter-regional migratory behaviour. The findings suggest that regional policy can have significant national spillover effects, even when the target region is small relative to the RUK. Furthermore, the configuration of the labour market is important in determining the post-shock adjustment path of both economies. In particular, while Scottish economy results are sensitive to alternative versions of how regional labour markets function, RUK region effects prove to be even more so

Regional Policy Spillovers: The National Impact of Demand-Side Policy in an Interregional Model of the UK Economy

UK regional policy has been advocated as a means of reducing regional disparities and stimulating national growth. However, there is limited understanding of the interregional and national effects of such a policy. This paper uses an interregional computable general equilibrium model to identify the national impact of a policy-induced regional demand shock under alternative labour market closures. Our simulation results suggest that regional policy operating solely on the demand side has significant national impacts. Furthermore, the effects on the non-target region are particularly sensitive to the treatment of the regional labour market.regional CGE modelling, migration, regional development policy

A note on the identification and transmission of energy demand and supply shocks

This paper proposes and implements a novel structural VAR approach for identifying oil demand and supply shocks. In this approach we search for two shocks in the context of a VAR model, which explain the majority of the k-step ahead prediction error variances of oil prices. Finally, we compare our approach with alternative identification schemes based on sign restrictions, and we show that the proposed methods is a useful tool for decomposing oil shocks
