Subsidies for renewable energy in inflexible power markets

This paper analyses how short-term operational efficiency and the \(\hbox {CO}_{2}\) emissions of a power system depend on different subsidies for wind power and on the flexibility of the power system. This is analysed in the framework of a numerical power market model, calibrated to Danish data, where the start-up costs and other constraints in fossil-fuelled power plants are taken into account. The main conclusion is that flexibility is crucial for the costs of integrating wind power in an existing system. If thermal power plants are inflexible, subsidies for wind power should strive to increase the flexibility of the market by passing market signals to wind power. A subsidy that conceals market signals from wind power producers (a production subsidy) or disconnects wind power incentives from the market signals altogether (a fixed price) increases costs considerably. An inflexible power system should aim to introduce optimal subsidies (an investment subsidy) instead of production subsidies or a fixed price. The design of the subsidy scheme should take into account both the characteristics of the existing system and the characteristics of renewables.     

Playing at markets: A New Austrian perspective on macroeconomic policy

The New Austrian (also called Neo-Mengerian) paradigm emphasizes the importance of nonequilibrium and emergent processes in explaining the social world. In this paper I analyze macroeconomic policy from a New Austrian perspective. I define macroeconomic policy broadly, encompassing not only policy relating to business cycles and growth, but to any policy aimed at directly manipulating emergent variables. Such policy is fundamentally incoherent, since it attempts to divorce social outcomes from the processes that generate them and give them meaning. A New Austrian approach to macroeconomic policy, which focuses on the rules structuring nonequilibrium-emergent social processes, avoids this problem.     

The role of labor markets for euro area monetary policy

In this paper, we explore the role of labor markets for monetary policy in the euro area in a New Keynesian model in which labor markets are characterized by search and matching frictions. We first investigate to which extent a more flexible labor market would alter the business cycle behavior and the transmission of monetary policy. We find that while a lower degree of wage rigidity makes monetary policy more effective, i.e. a monetary policy shock transmits faster onto inflation, the importance of other labor market rigidities for the transmission of shocks is rather limited. Second, having estimated the model by Bayesian techniques we analyze to which extent labor market shocks, such as disturbances in the vacancy posting process, shocks to the separation rate and variations in bargaining power are important determinants of business cycle fluctuations. Our results point primarily towards disturbances in the bargaining process as a significant contributor to inflation and output fluctuations. In sum, the paper supports current central bank practice which appears to put considerable effort into monitoring euro area wage dynamics and which appears to treat some of the other labor market information as less important for monetary policy.     

Trade policy with asset markets: The role of financial structure for time consistency

The present study uses a two-country, two-good, stochastic general equilibrium trade model to analyze the implications of optimal trade policy under uncertainty in the presence of financial markets. Using such a framework, I demonstrate that the policy-active home government, acting to maximize domestic welfare, will always have incentive to revise the previously announced import tariff policy once an asset position is taken by the representative agent in each country engaged in trade. The resulting time-consistent solution will be sensitive to the composition of asset income. Since the fiancial contracts can be combined in an infinite number of ways to yield the same optimal level of asset income, there will exist multiple time-consistent solutions, one for each financial structure. Using a specific log utility function, I also show that for certain financial structures, precommitment solutions will be replicated by time-consistent solutions, a result which marks a significant departure from the standard deterministic framework.     

Understanding the role of economic transition in enlarging energy price elasticity

Evidence of energy price elasticity would allow for a better understanding of economic, distributional and environmental consequences of varying energy prices. We document the previously unnoticed causal relationship between energy price elasticity and economic transition by modelling energy price elasticity as endogenous to the economic system. The central message is that economic transition promotes incentives and flexibility of micro‐units to sufficiently use price signals. Three potential mechanisms are proposed and tested for economic transition affecting the energy price elasticity. The findings provide implications for energy price policies because it reveals how energy consumers respond to energy price changes alongside economic transition.     

The price of the euro: evidence from sovereign debt markets

The objective of this article is to ascertain how the Economic and Monetary Union (EMU) in Europe has affected its members’ long-term government bond yields. In order to estimate the effect, this article utilizes a synthetic control approach. The main finding is that the majority of the member countries did not receive economic gains from the EMU in sovereign debt markets. Synthetic counterfactual analysis finds strong evidence that Austria, Belgium, Finland, France and the Netherlands have paid a positive and substantial euro-premium in their 10-year government bonds since the adoption of the single currency. After the most recent financial crisis, government bond yields have been higher in all member countries compared to the situation that would have occurred without the monetary unification. This article concludes that from the viewpoint of sovereign borrowing, it would be beneficial for a country to maintain its own currency and monetary policy.     

The role of financial speculation in the energy future markets: A new time-varying coefficient approach

To study whether speculating behavior plays an important role in oil futures markets, this paper proposes a time-varying coefficient version of the model of Llorente, Michaely, Saar, and Wang (2002) and estimates the effect of the speculating behavior using a sieve maximum likelihood estimation method. Using the time-varying coefficient model and the data of crude oil and heating oil futures markets, we find that neither the speculative motive nor the hedging motive dominates the markets over the whole sample period. However, we find that one of the two motives dominates the markets over some subsample periods. More importantly, speculation dominates in both the crude oil and heating oil futures markets around 2008. These empirical findings support the argument that the speculating behavior significantly affected the sharp rise in the price of crude oil in 2008.     

Competition and price dispersion in the airline markets

We use two ticket-level data sets on one-way domestic flights for the US airlines to examine the potentially nonlinear relationship between price dispersion and three forms of competition: inter-firm, inter-flight and frequency competitions. The linear relationship is rejected at any conventional significance levels. In particular, there is an S-shaped relationship between market concentration and price dispersion. This can be a reason for the mixed results in the literature. Roughly speaking, the inter-flight and frequency competitions have opposite effects on price dispersion. Finally, in general, the size of aircraft has a positive effect on price. However, for very large aircraft, the relationship becomes negative.     

Geographic price dispersion in retail markets: Evidence from micro-data

Using an extensive micro-price data of 266 retail goods and services across US, EU and OECD cities between 1990 and 2005, we study characteristics of geographic dispersion of deviations from the Law of One Price. We find that the magnitude of price dispersion is a function of the characteristics of both the type of good and set of locations under examination. Higher share of non-traded inputs and lower tradability of goods are both found to contribute to geographic price dispersion, with the former typically dominating in explanatory power. The role of tradability of good in accounting for the price dispersion is more significant as we move beyond an economic geography, while non-traded input level matters relatively more if we move to the interior of this geography. Our evidence suggests that the models of real exchange rates should incorporate the classical distinction between traded inputs and local inputs as well as a role for relative markups and traditional trade costs.     

Law of the jungle: firm survival and price dynamics in evolutionary markets

In this paper I develop a simple, and general model of supply and demand within which almost any theory of consumer and producer behaviour may be integrated by varying parameters. I then investigate the dynamics of this model and its implications for the theory of market evolution, and show that it unifies a number of insights from evolutionary economics. I extend upon these evolutionary theories and also characterise the distribution of prices across the market and investigate its evolution over time.     

The price of energy and potential growth of developed countries: An attempt at quantification

A growth model based on a theoretical discussion of the impact of oil prices on developed countries is used to predict the impact of higher prices of energy on the growth of developed countries. The results suggest that the growth impact is small, that domestic price policies may have a large impact on oil imports, and that the investment of foreign assets accumulated by oil producers may make a significant contribution to the GNP of OECD.     

The law of one price: an examination of price integration between Europe and regional markets in Africa

This study examines the degree of price-integration of equity indices between the major markets of Africa, namely Morocco, Tunisia, Egypt, Kenya, Nigeria, Namibia and South Africa with the European markets of London and Paris. Vector Autoregressive and Autoregressive Distributed Lag methods reveal that African markets are largely price-segmented. The only markets that are price-integrated have shared economic and financial institutions, such as Namibia and South Africa, and Egypt, Tunisia and France. The evidence suggests that development policy should be focussed on enhancing existing institutions rather than embarking prematurely on regional integration.     

The role of excess capacity in determining market power in natural gas transportation markets

The approval by FERC of a regulated natural gas pipeline’s market-based rate application depends upon the availability of substitute pipelines with sufficient capacity to maintain the current transport price. But how much alternate capacity is enough? Clearly, the price will not increase when alternate pipelines have unsubscribed capacity equal to the capacity of the applicant pipeline, since the applicant’s capacity is then perfectly substitutable. And indeed, FERC has approved market-based rates when this “complete-replacement” criterion has been met. However, complete-replacement is too stringent a condition and we determine precisely how much alternate capacity suffices to keep the price from rising.     

The price stability oriented monetary policy of the ECB: an assessment

The definition of price stability adopted by the ECB has recently been criticized in the literature, particularly for being unable to fully anchor inflation expectations and creating a deflation risk. In the paper empirical evidence is provided against these claims. Despite the unfavourable macroeconomic conditions for the euro area since 2001, monetary policy management has lead to the setting of the policy rate at levels compatible with trend inflation (the long-run inflation forecast) in the range 1–3%, and therefore without affecting negatively the inflation outlook.     

Competing at the frontier: The changing role of technology policy in Singapore's economic strategy

For an economy competing at the global frontier, an innovation-based growth strategy requires a well-developed technological infrastructure, a set of capabilities-focused technology policies, as well as an institutional environment that stimulates innovation and entrepreneurship. This paper examines the role played by science and technology policy in an economy's transition to an innovation-based growth strategy. We discuss the challenges governments face as they restructure economic institutions to deepen R&D capabilities and encourage technology creation. We review Singapore's experience in this regard and assess its ongoing efforts to remake itself to compete at the global frontier.     

Spatial price dependence by time scale: Empirical evidence from the international butter markets

The objective of the present work is to investigate price dependence (co-movement) in the international butter markets. This is pursued using monthly wholesale prices from Oceania and the European Union and two non-parametric tools, namely, the copulas and the wavelets. The empirical results suggest that: (a) The price linkages in the two butter-producing regions are weak in the short-run but they become much stronger in the long-run. (b) The time horizon (time scale) is relevant not only for the intensity but for the structure of price co-movement as well; in the long-run, there is an asymmetry in price dependence in the sense that strong positive shocks are transmitted with a higher intensity compared to strong negative ones.     

Auction markets for dispatchable power: How to score the bids

Competitive bidding for electric generating capacity is becoming based on economic dispatch rather than the PURPA must-take norm. Incorporating economic dispatch into bidding requires different price scoring procedures. The avoided cost of a dispatchable project is determined by the energy price offered. Price scoring methods based on a percentage of avoided cost approach are uneconomically biased against baseload projects, because they neglect the duration effects of their dispatch. This bias is illustrated in a simple model of economic dispatch. A number of utilities use the percentage of avoided cost method for dispatchable capacity. They can correct the bias by using a net benefits per kW measure of economic value.     

Public policy and the creation of active venture capital markets

We assess the effectiveness of different public policy instruments for the creation of active venture capital markets. Our methodology focusses on ‘innovation ratios’, defined to be the shares of high-tech, and of early stage, venture capital investments. We study a unique panel of data for 14 European countries between 1988 and 2001. We have several novel findings. First, we find no evidence of a shortage of supply of venture capital funds in Europe, a result which questions the effectiveness of the most widely used policy for fostering active venture capital markets. We also find other policies to be effective. In particular, the opening of stock markets targeted at entrepreneurial companies has a positive, large effect on the innovation ratios. Reductions in the corporate capital gains tax rate increase the share of both high-tech and early stage investment. A reduction in labor regulation also results in a higher share of high-tech investments. Finally, we find no evidence of an effect of increased public R&D spending on the innovation ratios.
