What’s powering wind? The effect of the U.S. state renewable energy policies on wind capacity (1994–2012)

As of 2012, 29 states had enacted a Renewable Portfolio Standard (RPS), while 37 states had at least one utility offering Green Power Purchasing (GPP) to their customers. The goal of both policies is to promote the adoption of clean, renewable energy. This article examines the influence of these polices on wind capacity across the United States from 1994–2012, a period of significant expansion of the wind generation market. The analysis focuses on wind because as compared with other modern renewable energy sources, wind is the only renewable energy source to make significant inroads into the U.S. electricity generation market. My findings indicate that while there have been significant increases in commercial scale wind generation capacity, neither RPS nor GPP programmes had a significant influence on within state wind capacity additions.     

Policy Shifts and Financial Instability in Emerging Markets

We explain periods of financial instability following drastic policy shifts within a Hayekian framework. Hayek emphasized that prices, established via the market process, help market participants to form coherent expectations about the future and coordinate plans with one another. In this paper, we elaborate on how policy shifts may undermine planning based on price signals and exacerbate uncertainty about the future, which can contribute to financial instability. Based on our postulated framework, we clarify how financial liberalization in the 1980s/1990s and the recent discretionary monetary policies in the advanced economies may have contributed to recurring episodes of financial instability in emerging markets. In particular, this paper provides an explanation for (1) why we observe financial instability mainly shortly following financial liberalization, and (2) why financial developments in the emerging markets are sensitive to unexpected monetary policy changes in the advanced countries in the current zero‐interest rate environment.     

Political Economy of Conditional Aid in a Federal Economy

This paper employs a political economy approach to model the joint determination of national and subnational sectoral protection in an open federal economy. Political interactions between special interest groups and policymakers as well as economic interrelationships between federal and state government policies are analyzed. The model is applied to study the effects of conditional financial assistance on policy‐making in the aid‐receiving federal economy. We find that policy‐based financial assistance to the federal government tends to reduce the extent of distortions resulting from the federal government policy. However, if federal and state government policies are strategic substitutes, state government induced policy distortions would increase, thereby detracting from the effectiveness of conditionality in reducing overall policy distortions in the recipient economy.     

THE RELEVANCE OF THE COOPERATIVE MODEL IN THE FIELD OF RENEWABLE ENERGY

While ‘traditional’ cooperatives operating for a long time in fields such as banking, agriculture, or retail, have received important attention in the cooperative literature, much work still needs to be done to understand why and how cooperatives emerge either in fields in which they have not traditionally been widespread (such as health and care, services, etc.), or in ‘new’ fields or sub‐fields (such as fair trade, microfinance or renewable energy). Research is even more needed insofar as ‘new’ cooperatives tend to differ from traditional ones in several ways, for instance through the involvement of multiple stakeholders (rather than a dominant one such as producers, consumers or workers) or through a stronger orientation towards general interest goals (beyond traditional mutual interest at the basis of most cooperatives). In this article, we analyze the emergence of cooperatives in the field of renewable energy. This emergence has raised a lot of enthusiasm among the supporters of cooperatives and citizen‐based renewable energy as well as questions regarding the viability and the replicability of this model. On the one hand, the assets of the cooperative model enable us to understand why this form has been adopted by citizen groups and has developed, although to varying extents, in many countries. On the other hand, the limits or weaknesses of the model enable us to explain why cooperatives are still a minority in the field of renewable energy and why their development is constrained by several obstacles.     

Bi‐currency versus Single‐currency Targeting: Lessons from the Russian Experience

This paper examines how the 2005 shift in Russian exchange rate policy from US dollar (USD) single‐currency to USD–EUR (euro) bi‐currency targeting has impacted domestic interest rates. The finding show that this policy shift has disconnected Russian interest rates from US dollar‐denominated interest rates, while instead linking them to a synthetic interest rate composed of USD and EUR rates at the same proportion as that of these two currencies in the currency basket against which the ruble's exchange rate is set. The Russian experience shows that while the adoption of bi‐currency targeting may help ensure that domestic interest rates are less dependent on the monetary cycle of a single country, these rates are instead likely to reflect financial developments in all countries whose currencies are included in the currency basket. This insight is likely to be relevant for other countries that pursue basket‐targeting policies.     

What Monetary Policy after the Crisis?

The objective of this paper is to reflect on some of the implications that recent economic experience has for monetary and financial stability policies. We contend that the financial crisis and the upsurge in inflation 2007–08 have shown that the policy model based on the new consensus in macroeconomics, which largely held sway over the past decade or more, is broken. It is argued that inflation targeting cannot deliver low inflation. We argue that fine-tuning through interest rates should not be attempted, but rather a constant real interest rate target based on the output growth rate should be adopted. The key objective of monetary policy should be shifted to financial stability, the independence of central banks should be brought to an end, and their decision making should be coordinated with other macroeconomic policy initiatives.     

Financial markets, specialization, and learning by doing

This paper considers three questions: (1) what is the role of financial markets in development, (2) why do some economies have such poorly developed financial markets, and (3) can government policy be used to promote financial market development? With respect to the first question, we formalize the widely-held notion that financial markets promote entrepreneurship, specialization, and learning-by-doing. However, if economic incentives for specialization are absent, financial markets may fail to form. This occurs when real interest rates are too low. We also discuss policies that can be used to promote financial market development. When these policies are successful, they will be growth promoting. Finally, we examine policies intended to manipulate returns on savings, which are often important components of “financial liberalizations”. We describe conditions under which such policies will be conducive to growth.     

Renewable energy subsidies: Second-best policy or fatal aberration for mitigation?

This paper evaluates the consequences of renewable energy policies on welfare and energy prices in a world where carbon pricing is imperfect and the regulator seeks to limit emissions to a (cumulative) target. The imperfectness of the carbon price is motivated by political concerns regarding distributional effects of increased energy prices. Hence, carbon prices are considered to be temporarily or permanently absent or endogenously constrained by their effect on energy prices. We use a global general equilibrium model with an intertemporal fossil resource sector and calculate intertemporally optimal policies from a broad set of policy instruments including carbon taxes, renewable energy subsidies and feed-in-tariffs, among others. If carbon pricing is permanently missing, mitigation costs increase by a multiple (compared to the optimal carbon pricing policy) for a wide range of parameters describing extraction costs, renewable energy costs, substitution possibilities and normative attitudes. Furthermore, we show that small deviations from the second-best subsidy can lead to strong increases in emissions and consumption losses. This confirms the rising concerns about the occurrence of unintended side effects of climate policy – a new version of the green paradox. Smart combinations of carbon prices and renewable energy subsidies, however, can achieve ambitious mitigation targets at moderate additional costs without leading to high energy price increases.     

Consumer support for environmental policies: An application to purchases of green cars

This paper focuses on how consumer motivation can be tapped in order to encourage the adoption of cleaner technologies. Consumers are heterogeneous — they may be guided by intrinsic motivation or extrinsic motivation. While information provision policies (such as the energy label for cars) may be effective in encouraging certain consumers to adopt green cars, financial incentive schemes (such as subsidies or fines) may be more persuasive for extrinsically-motivated consumers. We develop a dynamic theory of adoption of environmental innovations, in which information-provision policies are followed by financial incentives (first ‘carrot’, then ‘stick’ incentives). Analysis of a survey dataset of Swiss households observes considerable heterogeneity in terms of support of information-provision or financial incentive policies, in line with our conjectures. Our results will be of particular interest to policymakers interested in guiding consumers towards cleaner technologies.     

RIGHT ON TARGET: EXPLORING THE FACTORS LEADING TO INFLATION TARGETING ADOPTION

This paper examines which economic, fiscal, external, financial, and institutional characteristics of countries affect the likelihood that they adopt inflation targeting (IT) as their monetary policy strategy. We estimate a panel binary response model for 60 countries and two subsamples consisting of Organization for Economic Cooperation and Development (OECD) and non‐OECD countries over the period 1985–2008. The findings suggest that past macroeconomic performance of a country, its fiscal discipline, exchange rate arrangements, as well as the structure and development of its financial system have a significant impact on the likelihood to adopt IT. However, the factors leading to IT adoption differ significantly between OECD and non‐OECD countries. (JEL E42, E52)     

THE EFFECTIVENESS OF NON‐TRADITIONAL MONETARY POLICY MEASURES: THE CASE OF THE BANK OF JAPAN*

This paper summarizes non‐traditional monetary policy measures adopted by the Bank of Japan (BOJ) during the last 2 decades and by other G7 central banks since the start of the current global financial turmoil and analyses the effectiveness of such measures. The paper begins with a typology of policies usable near the zero lower bound on interest rates. They are: (i) forward guidance of future policy rates; (ii) targeted asset purchases; and (iii) quantitative easing. Using this typology, I review the measures adopted by the BOJ and other central banks. I then offer a news analysis of the effects of the measures adopted by the BOJ on asset prices, comparing them with those adopted by the Fed. Many of the measures, with the exception of strategy (iii), are shown to have moved asset prices in the expected directions. Another exception is that most of the monetary easing measures failed to weaken the yen. Despite some effects on asset prices, however, the measures have failed to stop the deflationary trend of the Japanese economy clearly. I discuss some possible reasons for this and more general implications for monetary policy.

Monetary policy tradeoffs between financial stability and price stability

We analyze the impact of interest rate policy on financial stability in an environment where banks can experience runs on their short‐term liabilities forcing them to sell assets at fire‐sale prices. Price adjustment frictions and a state‐dependent risk of financial crisis create the possibility of a policy tradeoff between price stability and financial stability. Focusing on Taylor rules with monetary policy possibly reacting to banks’ short‐term liabilities, we find that the optimized policy uses the extra tool to support investment at the expense of higher inflation and output volatility.     

Approximations in power transmission planning: implications for the cost and performance of renewable portfolio standards

Renewable portfolio standards (RPSs) are popular market-based mechanisms for promoting development of renewable power generation. However, they are usually implemented without considering the capabilities and cost of transmission infrastructure. We use single- and multi-stage planning approaches to find cost-effective transmission and generation investments to meet single and multi-year RPS goals, respectively. Using a six-node network and assuming a linearized DC power flow, we examine how the lumpy nature of network reinforcements and Kirchhoff’s Voltage Law can affect the performance of RPSs. First, we show how simplified planning approaches that ignore transmission constraints, transmission lumpiness, or Kirchhoff’s voltage law yield distorted estimates of the type and location of infrastructure, as well as inaccurate compliance costs to meet the renewable goals. Second, we illustrate how lumpy transmission investments and Kirchhoff’s voltage law result in compliance costs that are nonconvex with respect to the RPS targets, in the sense that the marginal costs of meeting the RPS may decrease rather than increase as the target is raised. Thus, the value of renewable energy certificates (RECs) also depends on the network topology, as does the amount of noncompliance with the RPS, if noncompliance is penalized but not prohibited. Finally, we use a multi-stage planning model to determine the optimal generation and transmission infrastructure for RPS designs that set multiyear goals. We find that the optimal infrastructure to meet RPS policies that are enforced year-by-year differ from the optimal infrastructure if banking and borrowing is allowed in the REC market.

Impact of energy infrastructure investments on renewable electricity generation in major Asian developing economies

The prime objective of this research is to empirically investigate the impact of energy infrastructure investments (public-private-partnership) on renewable electricity generation in major Asian developing economies (China, India, Indonesia, Malaysia, Pakistan, the Philippines, and Thailand). In doing so, we use the annual data of variables from 1993 to 2017. To achieve the study objective, the authors employ numerous panel econometric approaches such as the Grouped-Mean and Augmented Mean Group estimators. The overall conclusion of the findings is that investments in energy infrastructure play a significant role in promoting renewable electricity generation in Asian developing economies. The results also reveal that financial development, economic development, and openness further rise renewable electricity generation. Based on the findings, the authors attempted to provide novel implications for the promotion of energy infrastructure investments and sustainable development policies for the Asian developing economies. For instance, the authors suggest that governments and policy makers should realise the significance of greener energy and promote investments via public-private partnerships for renewable energy projects.     

Energy,unemployment and trade

This article investigates the dynamic relationships among sectoral economic activities, macro expenditure patterns, renewable and non-renewable energy consumption and unemployment in 41 countries from 1980 to 2014. The state of the art econometric techniques, both linear and non-linear panel and time series estimation techniques are used. The results show that industrialization, services sector, government expenditure and trade openness play a positive role in reducing unemployment, while agriculture and renewable energy consumption increase unemployment. This might be, in part, due to recent technological advancements and large capital intensive investments in agriculture and renewable energy sectors. Therefore, dedicated social and labour market policies need to be adopted to complement greening economic policies.     

Negative price spikes at power markets: the role of energy policy

In Germany, substantial drops in wholesale power prices have become a regular phenomenon. While such price drops have far-reaching implications for the functioning of the power market, their underlying determinants remain poorly understood. To fill this gap, we propose a Markov regime-switching model to investigate low-price events at the European Power Exchange. Our analysis focuses on the role of energy policies that promote renewable energies and have led to significant reductions of nuclear capacities after the Fukushima accident. We find that high electricity infeed from renewable sources increases negative price spike probabilities, while the decommissioning of nuclear plants under the Nuclear Moratorium had an opposing effect. Simulations of market outcomes under different energy policies indicate that reaching ambitious renewable energy targets increases the frequency of low-price events and compromises the financial viability of conventional generation units, while a nuclear phase-out or an increase in storage capacities mitigates these effects.     

The economic crisis of the 1990s in Finland

In the 1990s, Finland underwent a deep depression as its GDP dropped about 14% and unemployment rose from 3 to almost 20%. This is a story of bad luck and bad policies. Bad luck took the form of external shocks: the collapse of trade with the former Soviet Union in 1991, but also sharp cycles in the OECD area. However, bad luck is far from being the whole story. In the absence of bad policies, Finland would have experienced a recession, not a depression. Bad policies included a poorly designed financial regulation and mistaken reactions to the onset of the crisis. Of particular interest is the role of financial factors in triggering the crisis and aggravating the effects of bad policies. Not only were consumption and investment spending hurt by the credit crunch, but there is evidence that the private sector's indebtedness has increased structural unemployment, which explains why the recovery is proceeding with few job creations. A number of general lessons emerge. They concern the deregulation of financial markets, the policy reaction to massive capital inflows and the role of employment policies.     

The Role of Fiscal and Monetary Policies in Sustaining Growth With Stability in India*

The performance of the Indian economy in recent years has attracted increasing international interest. This paper focuses on the role of fiscal and monetary policies in the evolution of the Indian economy over the years, with particular attention being given to the reforms undertaken in these policies since the early 1990s. The coordination of fiscal and monetary policies has been crucial in the sequencing of the economic reform process carried out since the early 1990s. Monetary policy aims to maintain a judicious balance between price stability and economic growth. With the opening up of the Indian economy and the spread of financial sector reforms aimed at functional autonomy, prudential strengthening, operational efficiency, and competitiveness of banks, considerations of financial stability have assumed greater importance in recent years alongside the increasing openness of the Indian economy. The biggest challenge facing the conduct of fiscal and monetary policy in India is to continue the accelerated growth process while maintaining price and financial stability. Therefore, the self‐imposed rule‐based fiscal correction at both the national and subnational levels has to be consolidated and carried forward. The existence of a high level of fiscal deficit also contributes to the persistence of an interest rate differential with the rest of the world, which then also constrains progress toward full capital account convertibility. The success achieved in revenue buoyancy through tax rationalization and compliance has to be strengthened further.
