How do central banks react to wealth composition and asset prices?

We assess the response of monetary policy to developments in asset markets in the euro area, the US and the UK. We estimate the reaction of monetary policy to wealth composition and asset prices using: (i) a linear framework based on a fully simultaneous system approach in a Bayesian environment; and (ii) a nonlinear specification that relies on a smooth transition regression model.     

How have global financial institutions responded to the challenges of the post-crisis era?

The study examines the largely unexplored effect of changes in the competitive landscape for large, global financial institutions on their ability to take risks, as well as deploy capital and labour in an efficient manner based on a novel measure of inefficiency. The analysis shows during 2001–2013 that inefficiency peaked during the 2008 crisis period and has fallen back to levels close to pre-crisis periods. The model also performs well in out-of-sample forecasts of the financial firms’ future market values. These results suggest that large financial firms have been adjusting to the ‘new normal’ of the post-crisis period and thus are able to use capital and labour more efficiently within the constraints of current market conditions. In addition, a non-linear pattern between inefficiency and a firm’s asset size suggests that there might be an optimal scale for such firms in the $450–650 billion range.     

How do US credit supply shocks propagate internationally? A GVAR approach

We study how US credit supply shocks are transmitted to other economies. We use the recently developed GVAR approach to model financial variables jointly with macroeconomic variables in 33 countries for the period 1983–2009. We experiment with inter-country links based on bilateral trade, portfolio investment, foreign direct investment and banking exposures. Capturing both bilateral trade and financial exposures in a GVAR fits the data better than using trade weights only. We use sign restrictions on the short-run impulse responses in the US model to identify the credit supply shocks. We find that negative credit supply shocks have strong negative effects on US and foreign GDP. Credit and equity markets in several countries respond clearly to the shocks. Exchange rate responses are consistent with a “flight to quality” to the US dollar. The credit supply shocks explain about a fifth of one-year-ahead output forecast error variance in the US and about a tenth in the euro area and the UK, but considerably less elsewhere.     

Conservative central banks: how conservative should a central bank be?

Using Rogoff's, 1985 model, we determine how inflation averse a central banker should be, given the level of volatility and projected output gap in the economy. We confirm a strong degree of conservatism, almost twice what society would have chosen. But, for a range of developing countries and the OECD, economies that systematically experience higher levels of output volatility would do best to hire a central banker who is more inflation averse than society, but less so than in stable developed economies. Thus, while a conservative central banker remains desirable, the trade‐off is with output volatility rather than with the output gap itself.     

How do banks set interest rates?

This paper studies cross-sectional differences in banks interest rates. It adds to the literature in two ways. First, it analyzes systematically the micro and macroeconomic factors that influence the price-setting behaviour of banks. Second, by using banks’ prices (rather than quantities) it provides an alternative way of disentangling loan supply from loan demand shift in the “bank lending channel” literature. The results suggest that heterogeneity in the banking rates pass-through - depending on liquidity, capitalization and relationship lending - exists only in the short run.     

Do central banks affect Tobin's q?

Previous work has documented inflation effects on Tobin's q in the long run. This paper examines whether the FED's different policies and chairmen tenure have an impact on Tobin's q, after a modified stylized AD-AS model shows that central banks affect q. We do find changing responses of q depending on the pre-Volcker and post-Volcker periods.     

When does the cost channel pose a challenge to inflation targeting central banks?

In a sticky-price model where firms finance their production inputs, there is both a lower and an upper bound on the central bank's inflation response necessary to rule out the possibility of self-fulfilling inflation expectations. This paper shows that real wage rigidities decrease this upper bound, but coefficients in the range of those on the Taylor rule place the economy well within the determinacy region. However, when there is time-variation in the share of firms who finance their inputs (i.e. Markov-switching) then inflation targeting interest rate rules frequently result in indeterminacy, even if the central bank also targets output. Adding a nominal growth target to the policy rule can often alleviate this indeterminacy and therefore anchor inflation expectations.     

The cause of Danish unemployment: Demand or supply shocks?

We study the Danish unemployment experience 1905–92 using a common trends model with cointegration constraints. To justify the identifying assumptions about the cointegration vectors and the common trends we present a simple macroeconomic model of the labor market. The model determines the long run behavior of labor productivity, employment, unemployment, real product and real consumer wages. The empirical results give support for three cointegration relations and two common trends. Based on the economic model the trends are interpreted as representing labor productivity (technology) and labor supply. With unemployment being nonstationary, the common trends analysis indicates that labor supply shocks is the primary source for explaining the behavior of unemployment.

Do central banks respond to exchange rate movements? Some new evidence from structural estimation

This paper investigates the impact of exchange rate movements on the conduct of monetary policy in Australia, Canada, New Zealand, and the United Kingdom. We develop and estimate a structural general equilibrium model, in which monetary policy is represented as a simple rule and exchange rate pass‐through is incomplete due to the presence of local currency pricing and distribution services. We find that the Bank of Canada, the Reserve Bank of New Zealand, and the Bank of England have not adjusted interest rates in response to exchange rate movements since the adoption of inflation targeting, while our model selection results for Australia are less clear.     

Sovereign credit ratings and central banks: Why do analysts pay attention to institutions?

This paper studies the effect of the governance of modern central banks on the ratings assigned by the credit rating agencies Standard and Poor's and Moody's. Until recently, the rating process was not public. Even still, the factors or precise methodologies used by the agencies remain uncertain and analyst judgment remains important. We argue that, given uncertainty over the future paths of countries, the quality of the central bank governance serves as a useful heuristic for a stable and favorable country trajectory. In particular, the central bank's independence signals that the government is committed to general macroeconomic stability, including debt repayment. Additionally, central bank transparency clarifies who is the principal of the bank and provides information about how the central bank understands the economy and monetary policy. Finally, tensions between the central bank and the government, as reflected by irregular turnover of central bank governors, raise doubts about countries’ future prospects. Empirically, we use a variety of models, including mediation analysis, to ensure that the effect we identify stems from the central bank governance itself, as a heuristic for the future paths of countries, and not the central bank's direct contribution to the macroeconomy, as reflected in the available data.     

Are we ignoring supply shocks? A proposal for monitoring cyclical fluctuations

Although there are several mechanisms within theoretical models acknowledging that supply shocks can account for an important part of output fluctuations, even in the short-run, policy practitioners continue endorsing the idea that only demand shocks explain them. This article provides empirical evidence on several Latin American countries and the USA to show that the share of output variance explained by supply shocks in the short-run is substantial. It also offers a more agnostic implementation of the Blanchard–Quah type of structural analysis that focuses on policy evaluation. For this purpose, we propose constructing two indicators out of the historical decomposition of shocks: the goods market unbalance (GMU) and the total cyclical fluctuations (TCF). While GMU is an excess demand measurement that reveals the scope of the distortions caused by shocks, TCF, combined with GMU, helps to understand what type of shock is predominantly explaining (output and inflation) fluctuations. These two pieces of information provide a very different diagnosis than traditional output gaps and should guide monetary policy interventions more adequately. The agnosticism of this proposal has two aspects: the use of a different identification strategy and the assessment of the effects of both supply and demand shocks on output.

     

Macroeconomic shocks, unionized labour markets and central bank disclosure policy: How beneficial is increased transparency?

The paper investigates the implications of disclosure by the central bank to the private sector of information relating to the current realizations of macroeconomic disturbances. In the context of an economy in which the goods market is monopolistically competitive and where wages are set by atomistic unions, we find that greater precision of information provided to wage setters in respect of supply shocks has ambiguous welfare effects, both from the perspective of the social loss function and from the viewpoint of unions who act on the information. An important feature of the model is an externality in union wage setting which implies the outcome of the wage determination process is collectively inefficient.     

How should environmental policy respond to business cycles? Optimal policy under persistent productivity shocks

How should environmental policy respond to economic fluctuations caused by persistent productivity shocks? This paper answers that question using a dynamic stochastic general equilibrium real business cycle model that includes a pollution externality. I first estimate the relationship between the cyclical components of carbon dioxide emissions and US GDP and find it to be inelastic. Using this result to calibrate the model, I find that optimal policy allows carbon emissions to be procyclical: increasing during expansions and decreasing during recessions. However, optimal policy dampens the procyclicality of emissions compared to the unregulated case. A price effect from costlier abatement during booms outweighs an income effect of greater demand for clean air. I also model a decentralized economy, where government chooses an emissions tax or quantity restriction and firms and consumers respond. The optimal emissions tax rate and the optimal emissions quota are both procyclical: during recessions, the tax rate and the emissions quota both decrease.     

How much profit shifting do European banks do?

This paper studies whether and to what extent the largest and systemically relevant European multinational banks engage in profit shifting to lower their tax burden. We exploit unique data on bank operations reported on a country-by-country basis since 2015 in compliance with European legislation. The dataset contains information on profits, turnover, taxes paid and employment of bank affiliates worldwide, including tax and regulatory havens. In our empirical model, profits shifting incentives are captured through a weighted average of international tax rate differences between all countries where the bank is active. We find that international tax differences trigger the geographical distribution of profits within multinational banks, and that low tax jurisdictions, notably tax havens, attract disproportionately high profits. Our results suggest that, overall, 21% of profits is shifted. Moreover, profits in tax havens are 51% higher than they would be without tax-motivated profit shifting, pointing to a significant reduction of tax bases in high-tax countries.     

How does credit supply respond to monetary policy and bank minimum capital requirements?

We use data on UK banks׳ minimum capital requirements to study the interaction of monetary policy and capital requirement regulation. UK banks were subject to both time-varying capital requirements and changes in interest rate policy. Tightening of either capital requirements or monetary policy reduces the supply of lending. Lending by large banks reacts substantially to capital requirement changes, but not to monetary policy changes. Lending by small banks reacts to both. There is little evidence of interaction between these two policy instruments. The differences in the responses of small and large banks identify important distributional consequences within the financial system of these two policy instruments. Finally, our findings do not corroborate theoretical models that raise concerns about complex interactions between monetary policy and macro-prudential variation in capital requirements.     

Health shocks and consumption smoothing in rural households: Does microcredit have a role to play?

This paper estimates, using a large panel data set from rural Bangladesh, the effects of health shocks on household consumption and how access to microcredit affects households’ response to such shocks. Households appear to be fairly well insured against health shocks. Our results suggest that households sell livestock in response to health shocks and short term insurance is therefore attained at a significant long term cost. However microcredit has a significant mitigating effect. Households that have access to microcredit do not need to sell livestock in order to insure consumption. Microcredit organizations and microcredit therefore have an insurance role to play, an aspect that has not been analyzed previously.     

Why don't banks lend to Egypt's private sector?

Bank credit to Egypt's private sector decreased over the last decade, despite a recapitalized banking system and high rates of economic growth. Recent macro-economic turmoil has reinforced the trend. This paper explains the decrease based on credit supply and demand considerations by 1) presenting stylized facts regarding the evolution of the banks' sources and fund use in 2005 to 2011, noting two different cycles of external capital flows, and 2) estimating private credit supply and demand equations using quarterly data from 1998 to 2011. The system of simultaneous equations is estimated both assuming continuous market clearing and allowing for transitory price rigidity entailing market disequilibrium. The main results are robust to the market clearing assumption. During the global financial crisis, a significant capital outflow stalled bank deposit growth, which in turn affected the private sector's credit supply. At the same time, the banking sector increased credit to the government. Both factors reduced the private sector's credit supply during the period under study. After the trough of the global crisis, capital flowed back into Egypt and deposit growth stopped being a drag on the supply side, but bank credit to the government continued to drive the decrease in the private sector's credit supply. Beginning in the final quarter of 2010, capital flows reversed in tandem with global capital markets, and in January 2011 the popular uprising that ousted President Hosni Mubarak added an Egypt-specific shock that accentuated the outflow. Lending capacity dragged again, accounting for 10% of the estimated fall in private credit. Credit to the government continued to drain resources, accounting for 70–80% of the estimated total decline. Reduced economic activity contributed around 15% of the total fall in credit. The relative importance of these factors contrasts with that of the preceding capital inflow period, when credit to the government accounted for 54% of the estimated fall, while demand factors accounted for a similar percentage.     

Does labour supply respond to a flat tax?

We exploit the exogenous change in marginal tax rates created by the Russian flat tax reform of 2001 to identify the effect of taxes on the labour supply of men and women. We apply a weighted difference‐in‐difference regression approach and instrumental variables to estimate labour supply functions using a panel dataset. The mean regression results indicate that the tax reform led to a statistically significant increase in hours of work for men but had no effect on work hours for women. However, we find a positive response to tax changes in both tails of the female work hour distribution. We also find that the reform increased the probability of finding a job among both men and women. Despite significant variation in individual responses, the aggregate labour supply elasticities are trivial. This suggests that reform‐induced changes in labour supply are an unlikely explanation for the amplified personal income tax revenues that followed the reform.
