Dynamic optimal control of pollution abatement under emissions permit banking

In a recent work, Dragone et al. (2010) modeled an optimal control model of pollution abatement, and investigated the adoption of a tax levied on the firm's instantaneous contribution to the accumulation of pollution. In this paper, we extend the work of Dragone et al. (2010) by providing a dynamic optimal control model of pollution abatement with emissions permits banking, where the firm is allowed to purchase, sell and bank emissions permits given a finite planning horizon of length. Our objective is to find the optimal levels of the production, the pollution abatement investment and the quantity of emissions permits bought or sold in continuous time through the use of optimal control theory. We illustrate the results with a numerical example.     

Does the banking sector structure matter for credit procyclicality?

The aim of this paper is to investigate whether the banking sector structure matters in explaining credit procyclicality for 17 OECD countries over the 1986–2010 period. To this end, we first provide a detailed classification of the banking system structure through the use of a hierarchical clustering methodology. Relying on the estimation of panel VAR models and accounting for potential heterogeneity between countries, we then propose a measure of credit procyclicality based on the impulse-response function of credit to a shock in GDP. Our findings show that while credit significantly responds to shocks in GDP, the structure of the banking sector is not a key factor in assessing the procyclicality of credit for OECD countries.     

Intertemporal Emission Permits Trading Under Uncertainty and Irreversibility

This paper analyzes the effect of emission permit banking on clean technology investment and abatement under conditions where the stringency of the future cap is uncertain. We examine the problem of heterogeneous firms minimizing the cost of intertemporal emission control in the presence of stochastic future pollution standards and emission permits that are tradable across firms and through time. A firm can invest in clean capital (an improved pollution abatement technology) to reduce its abatement cost. We consider two possibilities: that investment is reversible or irreversible. Uncertainty is captured within a two period model: only the current period cap is known. We show that if banking is positive and marginal abatement costs are sufficiently convex, there will be more abatement and investment in clean technology under uncertainty than there would be under certainty and no banking. These results are at odds with the common belief that uncertainty on future environmental policy is a barrier to investment in clean capital. Moreover, under uncertainty and irreversibility, we find that there are cases where banking enables firms to invest more in clean capital.     

Financial development and financial openness nexus: the precondition of banking competition

We examine the dynamic relationship between financial development and financial openness using the pooled mean group estimator developed by Pesaran et al. (1999). Our results show that financial openness has a positive effect on financial development in the long run, but may have a negative effect in the short run. Using estimates of country-specific short-run coefficients, we also find that the adverse short-run effects of financial openness are associated with a lower degree of banking competition. The system GMM estimator also supports these findings, suggesting that the financial development and financial openness nexus is contingent on the degree of banking competition. A key policy implication is that a higher degree of banking competition is a precondition for financial openness to promote financial development.     

Estimating the speed of adjustment of European banking efficiency under a quadratic loss function

This paper investigates the speed of adjustment of cost efficiency to equilibrium level in the European banking industry. Our analysis provides for the first time insights into the process of convergence across European banking markets as measured by the speed of adjustment of cost efficiency. In particular, we employ a quadratic loss function specification based on forward-looking rational expectations to model the underlying dynamics of efficiency scores in the banking industry of the EU-15 region over the period 1998–2005. Results show that there is considerable variation in the speed of adjustment across banking systems, while over time it appears that continuing efforts to advance financial integration have led to some improvement in the speed of adjustment to the long-run equilibrium.     

Real effects of banking crises: Imports of capital goods by developing countries

We examine the hypothesis that banking crises have real effects on developing economies by reducing imports of capital goods. We test this hypothesis by estimating a model for the determinants of imports of capital goods by a panel of developing economies during 1961 to 2010. Our results suggest that not only do banking crises have statistically significant and economically important effects on imports of capital goods, but these effects increase the longer a banking crisis lasts. Imports of capital goods are a critical component of the capital stock and the production process in developing economies and, thus, our results highlight one important channel through which banking crises may hamper the growth prospects of these economies.     

BANKING UNION IN EUROPE: HOW MUCH CENTRALISATION IS NEEDED?

We examine the efficiency of banking regulation in a federation with two tiers of government and highly integrated banking systems. We assume that policy makers have incomplete information about banks’ true health, and banking sector turmoil can generate cross‐border spill‐over effects. We show that, in such an environment, the decentralisation of policy responsibilities for the regulation of banks can achieve the first‐best allocation and ensure financial stability. While national governments design banking regulations, the federal policy maker authorises inter‐regional income redistribution payments throughout the federation. Our results suggest that strengthening national responsibilities in banking regulation and supervision in the course of the further development of the European banking union may be advisable.     

Optimal Policy with Tradable and Bankable Pollution Permits: Taking the Market Microstructure into Account

This paper analyzes how the way emission permits are traded—their market microstructure—affects the optimal policy to be adopted by the environmental agency. The microstructure used is one of a quote driven market type, which characterizes many financial markets. Market makers act as intermediaries for trading the permits by setting an ask price and a bid price. The possibility of bank permits is also introduced in our dynamic two‐period model. We consider two models whether the market makers are perfectly informed about the technology of the producers or not. When the market makers have complete information, the equilibrium price of permits is the same as if the market is walrasian. When they are imperfectly informed, they may set a positive spread between bid and ask permit prices, which creates some inefficiency as the marginal abatement costs of polluters do not equalize. By allowing more flexibility in the use of the permits, banking may reduce the spread. Moreover, it may introduce price rigidities due to intertemporal arbitrage. In this framework, the circumstances under which banking should be allowed or not depend crucially on the evolution of the marginal willingness to pay for the environment.     

WTO accession,foreign bank entry,and the productivity of Chinese manufacturing firms

After China’s accession to the World Trade Organization (WTO) in December 2001, foreign banks are allowed to enter the Chinese banking market in phases. Using firm-level data from the National Bureau of Statistics of China which cover all state-owned and non state-owned manufacturing firms with sales over 5 million RMB, we examine the relationship between foreign bank entry and the industry-level productivity growth of China’s manufacturing sector. Our empirical results suggest that (a) on average, opening up a region for foreign bank entry has no impact on aggregate productivity growth, (b) however, industries more dependent on external finance grow faster after a region is opened up for foreign bank entry, and (c) these results are due to changes in technical efficiency rather than reallocation. Overall, this paper provides new evidence on the relationship between banking market structure and manufacturing productivity in a fast growing developing country.     

Banking crises and human rights

We examine the effect of banking crises on a country’s protection of basic human rights. Our results indicate that banking crises have a causal, substantive and robust negative effect on human rights, particularly in nondemocracies. This adds to our understanding of how economic shocks can politically destabilize countries.     

The Welfare Effects of Allowance Banking in Emissions Trading Programs

Permitting allowance banking in emissions trading programs can reduce expected compliance costs by giving capped firms flexibility to adjust the time path of abatement and to hedge against future uncertainty. Recent literature suggests that this compliance cost dividend is significant (Fell and Morgenstern Environ Resour Econ 47:275–297, 2010). Allowance banking may yield an environmental dividend (a) if the growth rate of marginal damages from emissions is less than the discount rate and (b) if emissions are lower in the short run as firms bank permits for use in later periods. A discrete, stochastic dynamic programming model is considered to simulate the two dividends of allowance banking in the context of the most recent Federal United States greenhouse gas cap-and-trade legislation. Simulation results show that under a range of parameter values, the environmental dividend has the same order of magnitude as the compliance cost dividend. Under the central set of parameters, allowance banking increases expected present value of benefits by about $350$ million dollars per year of the program. The environmental dividend, however, is completely eliminated if capped firms can borrow permits from future periods without limit.     

Nonlinearities and heterogeneity in environmental quality: An empirical analysis of deforestation

We use a panel data set of 59 developing countries over the 1972–1994 period to study the deforestation process. Relying on both parametric and semiparametric models, we examine nonlinearities and heterogeneity in the deforestation process. We first study the existence of an Environmental Kuznets Curve (EKC) and then analyze determinants of deforestation. Our data sample provides no evidence of an EKC. We also find that political institution failures may worsen the deforestation process in developing countries.     

Do banking system transparency and competition affect nonperforming loans in the Chinese banking sector?

The increasing importance of transparency practices and the improving status of bank competition in China are rarely explored in nonperforming loans (NPLs) literature. Thus, the purpose of this study is to examine banking system transparency and competition along with macroeconomic and bank-specific variables as determinants of NPL. We use the two-step system GMM dynamic panel model for Chinese banks based on annual data from 2000 to 2014. Our results indicate that high transparency in the Chinese banking system decreases poor-quality assets but not in the case of government-owned banks, whereas increase in competition increases NPL. Moreover, we find mixed results in the context of macroeconomics and bank-specific variables. Our study has practical implications in risk management practices and macro prudential policies.     

Incentives for Investment in Advanced Pollution Abatement Technology in Emission Permit Markets with Banking

We examine the incentives that firms have to invest in cleaner abatementtechnology when the banking of permits is allowed in emission permittrading schemes. We show that under certainty permit banking can distortincentives for investment and lead to a sub-optimal amount of investmentspending. Under imperfect information, aggregate abatement costuncertainty and investment irreversibility provide arguments for allowingbanking. We generalize the model to consider these, showing that somebanking is desirable but that it need not be the case that the privatebanking solution is optimal.     

Small business lending and credit risk: Granger causality evidence

Because of their opaque nature, SMEs are overly reliant on bank lending. Therefore, we examine whether banks' credit supply to SMEs are affected by their financial conditions. To this end, we employ a Granger causality analysis to examine whether there is an indication of a significant direction of determination between SME lending and non-performing SME loans. The results reveal no bidirectional relationship between SME lending and NPL for the entire banking sector. For Islamic banks, however, we find two-way linkages between these two parameters: a negative causation is running both from SME lending to NPL growth and from NPL to SME lending. Given Islamic banks' deposit-oriented funding practices and their adherence to profit-and-loss sharing principles, this finding suggests the presence of heightened market discipline within the Islamic banking system.     

The sequencing of reform in transition economies

In this paper, we examine the consequences of sequencing on the progress of reforms in transition economies. The paper uses panel logit models to determine whether or not progress in some reforms enhances the prospects for other reforms. We find that progress on small-scale privatization is associated with advances in several other reforms, perhaps because small-scale privatization creates lobbies for reform. Our estimations suggest that a comprehensive program of small-scale privatization is needed to stimulate large-scale privatization, trade, and banking reform in a country that has undertaken little reform. Moreover, if restructuring is to occur banking reform is necessary. We also find that relaxing the fiscal constraint stimulates large-scale privatization, restructuring, and trade reform. Finally, we find that negotiations about EU accession negotiations advance the transition but only in banking reform and competition policy.

Are Islamic Banks More Resilient During Financial Panics?

Islamic banking is one of the fastest growing segments of the financial sector in developing countries. Rapid growth of this segment is accompanied with claims about its relative resilience to financial crises as compared to conventional banking. However, little empirical evidence is available to support such claims. Using data from Pakistan, where Islamic and conventional banks co‐exist, we compare the behaviour of Islamic and conventional banks during a financial panic. Our results show that Islamic bank branches are less prone to deposit withdrawals during financial panics, both unconditionally and after controlling for bank characteristics. The Islamic branches of banks that have both Islamic and conventional operations tend to attract (rather than lose) deposits during panics, which suggests a role for religious branding. We also find that Islamic bank branches grant more loans during financial panics and that their lending decisions are less sensitive to changes in deposits. Our findings suggest that greater financial inclusion of faith‐based groups may enhance the stability of the banking system.     

Banks’ non-traditional activities under regulatory changes: impact on risk,performance and capital adequacy

Using the big six Canadian chartered banks quarterly financial statements and daily stock market data from 1982 to 2018, we examine the impact of non-interest income on Canadian banks’ risk, performance and capital under the different major regulatory changes made to the Bank Act of Canada. Our results show that Canadian banks’ expansion into non-traditional activities had slightly decreased their risks and significantly improved their performance benefitting from income diversification. Moreover, while adhering to capital adequacy regulation, reshuffling banks’ portfolio towards non-traditional activities did not reduce Canadian banks’ capital ratio. In spite of the re-regulation towards universal banking against ring-fencing, this feature buttresses the effectiveness of capital adequacy regulation in Canada in linking banks capital allocation with their risk taking.     

Fees and the Efficiency of Tradable Permit Systems: An Experimental Approach

The paper presents the results of an economic experiment in which the effects of fees on allocative efficiency of tradable utilization permits (e.g. pollution permits) are explored. Laboratory subjects (university students) play the roles of firms whose generic product requires a specific input or permits. Scarcity is exogenously introduced by a fixed supply of tradable production permits. Three treatments are compared: No fee imposed (N); a fixed tax per permit (T); and partial retraction of permits and subsequent redistribution by auction (A). Treatments T and A represent two different ways of imposing fees, which are designed to be revenue equivalent. Our results indicate that, after controlling for deviation of permit prices from a prediction based on fundamentals, fees have an impact on distribution of permits. Interestingly, a fixed tax enhances efficiency compared to the case of no fees while retraction and reallocation by auction tends to reduce efficiency. Apparently, subjects’ decision making is affected by the imposition of fees, but how and to what extent depends on the method used.     

Disease or utopia? Testing Baumol in education

Baumol’s Cost Disease offers a compelling hypothesis of rising unit costs in stagnant sectors, but increased productivity in progressive sectors may generate the same prediction through income effects. We examine quantity (rather than expenditure) data from the U.S. educational sector to distinguish between these explanations. Our results indicate significant negative impacts of manufacturing productivity on teacher–pupil ratios.
