Vertical structure and the risk of rent extraction in the electricity industry

This paper studies how competition and vertical structure jointly determine generating capacities, retail prices, and welfare in the electricity industry. Analyzing a model in which demand is uncertain and retailers must commit to retail prices before they buy electricity in the wholesale market, we show that welfare is highest if competition in generation and retailing is combined with vertical separation. Vertically integrated generators choose excessively high retail prices and capacities to avoid rent extraction in the wholesale market when their retail demand exceeds their capacity. Vertical separation eliminates the risk of rent extraction and yields lower retail prices.     

Interest-rate and calendar-time effects in money market fund and bank deposit cash flows

We examine the sensitivities of aggregate balances of retail and institutional money market funds (MMFs) and their potential substitutes, bank deposits, to changes in short-term interest rates while controlling for calendar-time effects. We find that institutional MMF and time deposit cash flows are sensitive to recent changes in short-term interest rates. Institutional MMF investors appear to take advantage of arbitrage opportunities created by MMFs using the amortized cost technique. Retail MMF investors are much less responsive to changes in interest rates.     

Interbank loans,collateral and modern monetary policy

This study develops a novel agent-based model of the interbank market with endogenous credit risk formation mechanisms. We allow banks to exchange funds through unsecured and secured transactions, which facilitates the flow of funds to the most profitable investment projects. Risk premiums result from banks׳ forecasting rules and depend on past performance of the benchmark risk factors and interest rates. Our model confirms basic stylized facts of the interbank interest rates and volumes. We also find that network structures within the secured market segment are characterized by the presence of dealer banks, while we do not observe similar patterns in the unsecured market. We perturb the model with exogenous shocks and policy scenarios which correspond to unconventional monetary policies.     

Do stock markets discipline US Bank Holding Companies: Just monitoring,or also influencing?

This paper presents evidence that bank managers adjust key strategic variables following a risk and/or valuation signal from the stock market. Banks receive a risk signal when they exhibit substantially higher (semi-)volatility compared to the best performing bank(s) with similar characteristics, and a valuation signal when they are undervalued relative to the average bank with similar characteristics. We document, using a partial adjustment model, that bank managers adjust the long-term target value of key strategic variables and the speed of adjustment towards those targets following a risk and/or negative valuation signal. We interpret this as evidence of stock market influencing. We show that our results are unlikely to be driven by indirect influencing by regulators, subordinated debtholders, retail or wholesale depositors. Finally, we show that the likelihood that banks receive a risk and/or valuation signal increases with opaqueness, managerial discretion and specialization.     

What do bank acquirers value in non-public bank mergers and acquisitions?

This study investigates what target, market, and acquirer characteristics influence book value multiples in 288 non-public bank acquisitions from 2001 Q3 to 2005 Q4. Multiples rise with acquirer size and capital ratios. Targets with high proportions of industry-adjusted core and large deposits have higher multiples. When using target variables relative to acquirers, multiples rise with higher proportions of core and large deposits, larger average bank size in the market, and relative growth in assets, loans, and deposits as well as market growth. In contrast to prior findings for public targets, acquirers do not pay premiums for target accounting performance.     

Balance sheet effects and original sinners’ risk premiums

This paper describes an empirical model of country risk premiums and their determinants, relying on recent theories of balance sheet effects. We approach the latter by introducing a novel approach to country risk premiums that assumes that nominal exchange rates can move away from or towards equilibrium exchange rates, which allows exchange rate movements towards equilibrium to stimulate favourable competitiveness effects as opposed to adverse balance sheet effects. We investigate eight European emerging economies that suffer from “original sin” over the period 2001–2013, using the pooled mean group estimator of the dynamic panel error correction model. This methodology improves estimation efficiency and model performance, but also allows differentiation between long- and short-run country risk premium determinants. We find that, in the long run, country risk premiums increase in response to higher inflation and a higher total debt-to-GDP ratio, while they move in the opposite direction when the real GDP growth rate rises. Our results suggest that, in the short run, higher external debt service caused by exchange rate depreciation, i.e. the balance sheet effect, and market volatility tends to raise risk premiums, while higher international reserves and the federal funds rate tend to decrease them. Moreover, we show that the negative balance sheet effect is much stronger than the potentially favourable competitiveness effect, and that the rise in risk premiums is not due to the increase in the size of external debt, but to the larger debt burden represented by balance sheet effects.     

Heterogeneity in bank pricing policies: The Czech evidence

We estimate the pass-through from market interest rates to bank interest rates using heterogeneous panel cointegration techniques to address heterogeneity at the bank level in the Czech Republic. The results indicate heterogeneity in bank pricing in the short, but not in the long term. Mortgage rates and firm rates typically adjust to money market changes, but often less than fully in the long run. Large corporate loans have a smaller mark-up than small loans. Consumer rates have a high mark-up and do not exhibit a cointegration relationship with money market rates even in the long run. Next, we examine how bank characteristics determine the nature of interest rate pass-through in a cross-section of Czech banks. We find evidence for relationship lending, as banks with a stable pool of deposits smooth interest rates and require a higher spread as compensation. Large banks are not found to price their products less competitively. Greater credit risk increases vulnerability to money market shocks.     

Factors influencing bank risk in Europe: Evidence from the financial crisis

We use a dynamic panel data model to analyze bank-specific and macroeconomic determinants of bank risk for a large sample of commercial banks operating in the euro area. The selected time span, from 2001 to 2012, considers the impact of the on-going financial and economic crisis on the Eurozone banking system. Our results indicate that capitalization, profitability, efficiency and liquidity are inversely and significantly related to bank risk. However, the recourse to wholesale funding by banks seems to increase their risk. We also find that less-concentrated markets, lower interest rates, higher inflation rates and a context of economic crisis (with a falling GDP) increase bank risk.     

The impact of bank competition and concentration on bank risk-taking behavior and stability: Evidence from GCC countries

This paper presents a comprehensive assessment of the impact of competition on bank fragility pre and post financial crisis period in the GCC banking market as measured by bank risk-taking behavior and bank stability during the period 1998–2016. Our results indicate that a higher level of bank competition and the greater degree of concentration adds to financial fragility. The findings further shows that during the 2008 crisis, lower bank competition maintain the stability of GCC banks. We also find that lower level of competition and lower concentration in the banking market increases the risk-taking behavior of the low capitalized, low liquid and small banks which add to fragility in the banking system. Our findings suggest that countries with greater capital stringency, greater supervisory power, greater market discipline, and private monitoring, with explicit deposit insurance schemes, higher shareholder protection, and higher legal efficiency decrease banks’ risk-taking and increase their stability. We also find that greater regulatory restrictions and higher creditor protection decrease banks’ stability and increase risk in concerned countries. We find support for both competition-fragility and competition-stability hypotheses in the GCC banking market. The results also confirm that the use of a single measure of competition is insufficient to assess the role of competition in banking stability.

在发达的金融市场上,回购利率的期限结构服从纯预期假设,无论从经济意义上还是从统计意义上来说风险溢酬都不显著。但是中国金融市场作为新兴市场表现出一些不同点。本文利用2000年1月到2006年2月上海证券交易所的回购数据,发现长期回购利率有明显的风险溢酬,预期理论并不成立。进一步分析得到流动性是影响风险溢酬的一个关键因素,流动性的预期和流动性的随机冲击都对观察到的风险溢酬有影响,并且流动性的预期是主要的影响因素。     

Transparency of Retail Energy Pricing: Evidence from the US Natural Gas Industry

We test and cannot reject the hypothesis that retail pricing of natural gas is transparent for commercial and residential customers served by regulated local distribution companies in the United States. The periods of adjustment to a wholesale price change are 1.54 months for the commercial price and 1.69 months for the residential price. These findings support the view that regulated local distribution companies quickly adjust retail prices to fully capture any change in the wholesale natural gas price.

The federal funds market,excess reserves,and unconventional monetary policy

Following the bankruptcy of Lehman Brothers, interbank borrowing and lending dropped, whereas reserve holdings of depository institutions skyrocketed, as the Fed injected liquidity into the U.S. banking sector. This paper introduces bank liquidity risk and limited market participation into a real business cycle model with ex ante identical financial intermediaries and shows, in an analytically tractable way, how interbank trade and excess reserves emerge in general equilibrium. Investigating the role of the federal funds market and unconventional monetary policy for the propagation of aggregate real and financial shocks, I find that federal funds market participation is irrelevant in response to standard supply and demand shocks, whereas it matters for “uncertainty shocks”, i.e. mean-preserving spreads in the cross-section of liquidity risk. Liquidity injections by the central bank can absorb the effects of financial shocks on the real economy, although excess reserves might increase and federal funds might be crowded out, as a side effect.     

Identifying permanent and transitory risks in the Chinese property insurance market

This paper develops a theoretical model to identify various risks in the Chinese property insurance market. Consequently, we apply a structural VAR model to quantify the magnitude, historical timing of these risks, and their dynamic impacts on the permanent and transitory components of the insurance premiums. The results indicate that the enormous amount of speculative funds flowing into China has aggravated insurance premiums as well as helped accelerate market volatilities due to its uncertain nature to the domestic economy and its short-term characteristic of investing. In particular, the speculative shock is shown to be the primary factor responsible for the transitory fluctuation of insurance premiums while the supply shock explains the preponderance of insurance premiums’ permanent growth in recent years.     

Federal Home Loan Bank advances and bank risk

The Federal Home Loan Bank system (FHLB) has evolved into a major source of liquidity for the banking system with the demonstrated ability to borrow over a trillion dollars in world financial markets based on an implied U. S. Treasury guarantee. The FHLB loans the borrowed funds to commercial banks at reduced rates that are not adjusted for the risk of an individual bank. Moral hazard could cause member banks using FHLB loans to increase financial leverage and exposure to high risk assets. Conversely, the FHLB offers banks additional liquidity and specialized debt instruments that help them manage interest rate risk. We use dynamic panel generalized method of moments estimation to test the relation between FHLB advances and bank risk. We find that if banks have relatively normal default probabilities, advances are not associated with increased bank risk but, instead, advances are related to decreased interest rate risk. However, when bank default probabilities are high, our evidence suggests advances and higher bank risk are related.

THE DESIGN OF MUNICIPAL DEVELOPMENT FUNDS

Municipal Development Funds (MDFs) have become the preferred means of many donors and, increasingly, national governments for the finance of urban infrastructure. This article assesses their performance and design based on extensive data collection on ten MDFs and recommends changes. MDFs have two overall goals: credit and development. The greatest appeal of MDFs as credit providers is that they can wholesale funds for a wide variety of small urban infrastructure project to many local governments. However, they have largely failed to move toward market principles, and, too often, have succeeded in building infrastructure without strategically promoting local development. In this context, donors have focus sed on gearing MDFs to promoting local development - improving project appraisal, rationalizing the inter-governmental transfer system, establishing capital budgeting and fiscal planning, distributing funds among regions and municipal-size categories, and promoting community participation. But MDFs have also produced uneven results in achieving these goals. At bottom, MDFs have failed to connect with local demand. Local governments often have little idea what local people - particularly poor communities - want and need. Not surprisingly, they often fail to accept or repay charges for MDF projects. The best hope for improving MDFs lies in relating these funds closer to local people's preferences. Means to this end include: involving neighborhood associations and households in project selection; relying on project revenues rather than transfers as the main guarantee and source for loan repayment; using commercial financial institutions to underwrite, disburse, and collect loans; and hiring community development staff at the MDF.     

The impact of government intervention on the stabilization of domestic financial markets and on U.S. banks’ asset composition

The 2007–2009 financial crisis that evolved from various factors including the housing boom, aggressive lending activity, financial innovation, and increased access to money and capital markets prompted unprecedented U.S. government intervention in the financial sector. We examine changes in banks’ balance sheet composition associated with U.S. government intervention during the crisis. We find that the initial round of quantitative easing positively impacts bank liquidity across all bank samples. Our results show a positive impact of repurchase agreement market rates on bank liquidity for small and medium banks. We conclude that banks have become more liquid in the post-crisis period, especially the larger banks (large and money center banks). We show that real estate loan portfolio exposures have reverted to pre-crisis levels for money center banks and remained flat for all other bank samples.     

A model of vertical integration and investment in generation capacity in electricity markets: The case of the bidding game

The aim of this work is to assess the impact of (partial) vertical integration between generators and retailers on generation capacity choice and its subsequent welfare consequences. We present a framework in which final demand is perfectly inelastic and stochastic. Nevertheless, wholesale demand is elastic because of the existence of outside opportunities (mainly international transmission capacity). The model is a three-stage game. Neither transmission nor retail costs are taken into account.

In the first stage of the game, generators choose capacity only knowing distribution of demand and thus maximizing their expected profit. The second stage of the game represents the competition for market share between retailers in a market where consumers have switching costs. The former face unknown demand and maximize their utility based on two factors: the expected profit and a risk element. Finally, generators submit bid functions to the system operator given known demand and maximizing their profit during the last stage of the game. Retailers and generators interact in the wholesale market, which is cleared by the system operator whose function is to match supply (represented by the bids of the generators) and demand through a system of single price auctions. The wholesale market is the only means to buy and sell energy; there are no bilateral contracts between firms, except if they are vertically integrated.

We compare fully disintegrated and partially vertically integrated structures using a comparative statics approach. In this paper, the analysis will focus on the last stage of the game: the bidding game. We find that partial vertical integration between generators and retailers tends to lower wholesale prices but not unambiguously. Depending on which firm (vertically integrated or disintegrated generator) has installed the higher capacity and depending on level of demand, prices can stay unchanged or even rise.     

The reaction of financial markets to changes in FDIC policies on bank failures

The decade of the eighties was the most turbulent era for commercial banks since the Great Depression. Various bank-related events contributed to this agitation including deregulation, astronomical interest rates, massive bailouts, and great uncertainty. In this study the researchers examine the effects of these events on the cost of the leading source of funds for the banking industry during this period—purchased funds. The results indicate the pricing structure of the federal funds market reacts more to changes in Federal Reserve policy regarding monetary growth and economic stabilization activity than to particular bank problems.
