Governments,Exports and Growth: Responding to the Challenges and Opportunities of Globalisation

We live in an increasingly globalised world. Trade has consistently grown faster than GDP and has been an important driver of world growth. What role should government play in this process? This paper considers the rationale for government action and the merits of various policies focusing on the UKs experience: the benefits of openness to trade and overseas investment and the merits of tackling barriers that discourage greater participation by firms in international markets. It also considers whether this approach needs to be adapted given current trends in globalisation, concluding that a continued emphasis on openness and addressing market failures will be welfare enhancing.     

Greenhouse abatement policy: insights from the G-cubed multi-country model

The third meeting of the Conference of the Parties of the Framework Convention on Climate Change held in Japan last December was a lost opportunity to set a realistic policy framework for addressing climate change in the coming decades. A number of countries proposed targets for greenhouse emissions, to be reached by a target date. The outcome was a range of different targets for each country. Analysis with the G-cubed multi-country model suggests that fixed targets are a costly way to address climate change. The extent of potential cost suggests the agreement will eventually fail. A better way to address climate change is to focus on uniformity in policy instruments that deliver differentiated outcomes rather than focus on differentiated policy settings.     

Long term projections of carbon emissions

Future scenarios of climate change depend on the projections of greenhouse gas emissions, which are highly uncertain. A framework for projecting emissions should focus on the sources of economic growth and the changing structure of the global economy over time. It also requires an understanding of key historical and statistical issues, including the role of convergence assumptions and the appropriate basis of comparisons between countries. This paper presents a methodology developed using the G-Cubed multi–country model in which the economic structure and emissions outcomes are determined simultaneously. In order to illustrate the importance of the assumptions underlying the way these long term carbon projections are produced we also explore the debate around the “Castles and Henderson Critique” of the Special Report on Emission Scenarios (SRES) regarding the use of Market Exchange Rates (MERs) rather than Purchasing Power Parity exchange rates (PPPs) for benchmarking income differentials in the world economy. We show that under one scenario, emission projections based on convergence assumptions defined in MER terms are 40% higher by 2100 than emission projections based on PPP comparisons of income differentials. While this result can not necessarily be generalized to all forecasting frameworks, the potential magnitude of the difference suggests that this is a significant issue for such projection efforts.     

Comparing the global performance of alternative exchange arrangements

This paper presents and applies a methodology useful for studying the operating characteristics of a number of alternative monetary arrangements using a large-scale simulation model of the world economy. We consider the performance of the regimes when policymakers do or do not observe the shocks, and when policymakers infer the shocks using an optimal filtering rule. Although the results are model specific and at best illustrative of the issues involved, the approach does have the advantage of providing a richer framework of analysis than is possible in simple models of international interdependence.     

Farmers, government, and the environment: the settlement of Australia's 'wet frontier', 1870–1920

Historical studies of Australian agriculture have tended to concentrate on the difficulties of farming in a dry environment. The extension of farming into high-rainfall, densely forested regions (what I term the wet frontierc ) has been almost completely overlooked. This article is an attempt to redress this imbalance. It concentrates on the settlement of the wet frontier between 1870 and 1920. Up to about 1890 settlement was slow and often unsuccessful because of the high cost of forest clearance, environmental problems, deficiencies in transport, and government hostility and indifference. However, after 1890 increased demand for butter and improvement in dairy production technology transformed the wet frontier into a highly productive agricultural region.     

Dividend payout and executive compensation: theory and evidence from New Zealand

Using a model based on Bhattacharyya (2007), we predict a positive (negative) relationship between the earnings retention ratio (dividend payout ratio) and managerial compensation. We use tobit regression to analyse data for New Zealand firms' dividend payouts over the period 1997–2015 and find results consistent with Bhattacharyya (2007). These results hold when the definition of payout is modified to incorporate both common dividends and common share repurchases. Our results indicate that corporate dividend policy among New Zealand firms is perhaps best understood by considering the dividend payout ratio, rather than the level of, or changes in, cash dividends alone.     

Korean Unification: Economic Adjustments under German Assumptions

This paper explores the impact of unification on North and South Korea under the hypothetical scenario that German‐type reunification occurs in the Korean peninsula. Simulation results using a global dynamic general equilibrium model show that with comprehensive market‐oriented reform and opening, the North Korean economy could capitalize on its growth potentials. Unification can reduce the growth rate in South Korea for a certain period following the unification shock due to the transfer of resources out of the South into the North and an increase in risk on the Korea peninsula. Due to the relative sizes in population and per capita gross domestic product of the two Koreas, unification can be more disruptive on North and South Korea, compared to the experience of Germany. The critical factors determining the economic effects of unification are the nature of wage‐adjustment, the size of resource transfers from the South to North, and exchange rate policy.     

Monetary and Fiscal Stabilization of Demand Shocks Within Europe

This paper examines alternative macroeconomic stabilization rules for demand shocks, for a single open economy, and for an integrated European region. These questions are tackled in two ways. First a very simple macroeconomic model is used to focus on intercountry interconnections. Then the effects of shocks are simulated using the McKibbin Sachs MSG2 global economic model. The theoretical model analyzes just how much larger the disturbances caused by asymmetric shocks might be in a European Monetary Union, as compared with outcomes under floating exchange rates, especially (1) if rigid central monitoring and discipline of the fiscal policy prevents the full operation of the inbuilt fiscal stabilizers within individual European countries, and (2) if European monetary policy does not concern itself with fully European objectives. Simulations with the MSG2 model bear out the significance of these risks. They show that a demand shock like GEMU can have strongly negative effects on output in other European countries if either interest rates are raised to counter the demand shock in the originating country, or if, for some reason, fiscal stabilization is not allowed to be as strong as the inbuilt fiscal stabilizers.     

Monetary and Fiscal Policy-Makers in the European Economic and Monetary Union: Allies or Adversaries?

Optimal monetary and fiscal policies within the European Economic and Monetary Union (EMU) are determined by simulating a global model under alternative assumptions about the objective function of the European Central Bank (ECB) and about cooperation vs. non-cooperation between monetary and fiscal policy-makers and among the latter. The results show the high effectiveness of fixed rules in the presence of supply-side shocks and the usefulness of cooperative discretionary measures against demand-side shocks. More generally, cooperation among fiscal policy-makers in the EMU is nearly always superior to non-cooperative equilibrium solutions, yielding a strong case for the coordination of fiscal policies.
