CENTRAL BANK POLICIES AND INCOME AND WEALTH INEQUALITY: A SURVEY

This paper reviews recent research on the relationship between central bank policies and inequality. A new paradigm which integrates sticky‐prices, incomplete markets, and heterogeneity among households is emerging, which allows for the joint study of how inequality shapes macroeconomic aggregates and how macroeconomic shocks and policies affect inequality. The new paradigm features multiple distributional channels of monetary policy. Most empirical studies, however, analyze each potential channel of redistribution in isolation. Our review suggests that empirical research on the effects of conventional monetary policy on income and wealth inequality yields mixed findings, although there seems to be a consensus that higher inflation, at least above some threshold, increases inequality. In contrast to common wisdom, conclusions concerning the impact of unconventional monetary policies on inequality are also not clear cut. To better understand policy effects on inequality, future research should focus on the estimation of General Equilibrium models with heterogeneous agents.     

Differing behaviours of forecasters of UK GDP growth

The literature suggests that the dispersion of agents’ forecasts of an event flows from heterogeneity of beliefs and models. Using a data set of fixed event point forecasts of UK GDP growth by a panel of independent forecasters published by HM Treasury, we investigate three questions concerning this dispersion: (a) Are agent’s beliefs randomly distributed or do agents fall into groups with similar beliefs? (b) as agents revise their forecasts, what roles are played by their previous and consensus forecasts? and (c) is an agent’s private information of persistent value? We find that agents fall into four clusters, a large majority, a few pessimists, and two idiosyncratic agents. Our proposed model of forecast revisions shows agents are influenced positively by a change in the consensus forecast and negatively influenced by the previous distance of their forecast from the consensus. We show that the forecasts of a minority of agents significantly lead the consensus.     

Multilateral aggregation-theoretic monetary aggregation over heterogeneous countries

We derive fundamental theory for measuring monetary service flows aggregated over countries within a multicountry area. We develop three increasingly restrictive approaches: (1) the heterogeneous agents approach, (2) the multilateral representative agent approach, and (3) the unilateral representative agent approach. These results are being used by the European Central Bank in construction of its Divisia monetary aggregates database, with convergence from the most general to the more restrictive approaches expected as economic convergence within the area proceeds. Our theory permits monitoring the effects of policy over a multicountry area, while also monitoring the distribution effects of policy among the countries.     

Monetary policy transparency in a forward-looking market: Evidence from the United States

Because unsatisfactory measures of the monetary policy transparency were used, the existing literature found mixed empirical results for the relationship between the monetary policy transparency and risk/volatility. This paper extends the literature by using a recently developed monetary transparency index [Kia’s (2011) index] which is dynamic and continuous. Furthermore, the existing literature ignores the fact that market participants can be forward looking and, therefore, not policy invariant. This study also finds that the agents in the market are not policy invariant and the more transparent the monetary policy is the less risky and volatile the money market will be.     

THE REGIONAL EFFECTS OF MONETARY POLICY: A SURVEY OF THE EMPIRICAL LITERATURE

This survey provides an updated review of the empirical literature on the regional effects of monetary policy in economic activity by means of undertaking a threefold perspective. First, the main methodological dimensions of this literature are examined while pinpointing those modelling or methodological traits that constitute a source of diverging estimates and thereby produce inconclusive evidence. Secondly, the estimates yielded by the literature are summarized by carrying out a cross‐study analysis of the results for each monetary union. By drawing on empirical regularities that are robust across studies, the conclusiveness of the results is assessed, while those monetary unions for which conclusive evidence is still lacking are also identified. Lastly, the sources of regional heterogeneity identified by these studies are reviewed in order to shed some light on the linkage between monetary policy and territorial heterogeneity. As a result of this threefold perspective, this survey delivers overall structured conclusions and updated policy‐relevant lessons. Moreover, various research gaps and emerging topics in the literature are also identified.     

The effects of monetary policy in Russia: A factor-augmented VAR approach

Using factor-augmented vector autoregressive (FAVAR) models, this study examines the effects of the Central Bank of Russia’s (CBR) monetary policy on economic indicators. The sample includes 39 monthly macroeconomic series and covers the period 2004 through 2019. The analysis revealed counter-intuitive results, with consumer prices often responding positively to a contractionary monetary policy shock, and vice versa; this is related to the impossible trinity. The ruble exchange devaluation was accompanied by price increases through an import price pass-through, so the CBR chose exchange stability and free capital flows out of the impossible trinity, temporarily subordinating monetary policy independence. Such independence was limited, possibly due to Russia’s high dependence on energy exports and the link between energy prices and the exchange rate. The findings indicate no direct evidence of an effect of monetary policy tightening on the decrease in consumer prices; rather, the attenuation of ruble depreciation may have helped to stabilize prices, even after the CBR adopted inflation targeting.     

Organizational Control and Work Effort – Another Look at the Interplay of Rewards and Motivation

Providing rewards is a central element of organizational control systems. However, the literature is hardly helpful from a practitioner's perspective: it typically focuses on monetary rewards at the expense of non-monetary, affiliative rewards, and yet researchers disagree over the usefulness of the prior ones. Some scholars claim that monetary rewards merely replace task-related (‘intrinsic’) motivation by reward-induced external pressure (‘extrinsic’ motivation). Empirical findings are mixed, partially given the different conceptualizations of intrinsic motivation. We shed more light on the impact of both monetary and non-monetary, affiliative rewards on the willingness to exert work effort and a potential detrimental interaction with different forms of intrinsic motivation. Our experimental results suggest that monetary and affiliative rewards have different effects: affiliative rewards clearly have beneficial effects, whereas the picture for monetary rewards is more nuanced than typically assumed in literature.     

Childhood and capability deprivation in Italy: a multidimensional and fuzzy set approach

In the last decades, starting with the United Nations Convention on the Rights of the Children in 1989, children’s quality of life have received a growing attention in scientific research, as well as in politics. This work aims to gain insights into Italian children’s living conditions and deprivation of capabilities using the Capability Approach, an alternative normative framework for the evaluation of human development, well-being and freedom by thinking in terms of human functionings and capabilities. From a methodological point of view we present an approach based on a fuzzy methodology applied to data from the EU-SILC 2009 ad-hoc module on children. The use of this methodology makes it possible to preserve the richness of the data available from the EU-SILC survey, that include both monetary and non monetary aspects of children deprivation. To get more insides into Italian children living conditions we also combine the fuzzy methodology with the capability approach at a disaggregated level of analysis by three social economic factors (single parent household, household educational level, macro-region of residence). Besides the well-known Italian North/South disparity of financial indicators—confirmed also for households with children—our findings suggest a new duality for Italian children quality of life, given by the multidimensional domains of deprivation internal or external to children’s households.     

Heterogeneous expectations in the gold market: Specification and estimation

The increase in the price of gold between 2002 and 2011 appears to be a candidate for a potential asset price ‘bubble’, suggesting that chartists (feedback traders) were highly active in the gold market during this period. Hence, this paper develops and tests empirically several models incorporating heterogeneous expectations of agents, specifically fundamentalists and chartists, for the gold market. The empirical results show that both agent types are important in explaining historical gold prices but that the 10-year bull run of gold in the early 2000s is consistent with the presence of agents extrapolating long-term trends. Technically this paper is a further step toward providing an empirical foundation for certain assumptions used in the heterogeneous agents literature. For example, the empirical results presented in this paper compare the economical and statistical significance of numerous switching variable specifications that are generally only introduced ad hoc.     

A survey on time-varying parameter Taylor rule: A model modified with interest rate pass-through

Today, the prime aim of central banking is to achieve price stability and, to a lesser extent, output stability. To this end, central banks use various monetary policy rules. This paper intends to provide a broad survey of the literature on Taylor-type monetary policy rules with a time-varying parameter (TVP) specification. To include the TVP feature, some modification is made in the monetary transmission mechanism of Taylor-type monetary policy models to account for the changing risk preference of individuals. In line with this approach, we introduce an interest rate pass-through specification of the monetary transmission process in a general equilibrium model to account for the varying perceptions of risk by individuals. We include an application for Turkey and estimate the time-variable parameters of the model by employing a structural extended Kalman filter (EKF). The results indicate that the EKF performs better than the standard Kalman filter in estimating the reaction function of the central bank.     

Monetary policy,asset prices and consumption in China

This paper studies the wealth channel in China. Although the wealth channel has been found to be functioning in many advanced countries, its existence is yet to be explored in most emerging economies, also in China. In order to illuminate dynamics between monetary policy, asset prices and consumption, we use the structural vector autoregression method. The findings support the view that a loosening of China's monetary policy does indeed lead to higher asset prices. Furthermore, a positive shock to residential prices increases household consumption, while the role of stock prices seems to be small from the households’ point of view. Finally, we test the existence of the wealth channel more formally to find out whether those changes in asset prices that are caused by monetary policy are significant enough to increase consumption. In summary, the wealth channel remains weak but there are some signs of it via residential prices. The results are not that different from those attained for the advanced economies, where the size of the wealth channel has been found to be limited.     

Managing security risks for inter-organisational information systems: a multiagent collaborative model

Information sharing across organisations is critical to effectively managing the security risks of inter-organisational information systems. Nevertheless, few previous studies on information systems security have focused on inter-organisational information sharing, and none have studied the sharing of inferred beliefs versus factual observations. In this article, a multiagent collaborative model (MACM) is proposed as a practical solution to assess the risk level of each allied organisation’s information system and support proactive security treatment by sharing beliefs on event probabilities as well as factual observations. In MACM, for each allied organisation’s information system, we design four types of agents: inspection agent, analysis agent, control agent, and communication agent. By sharing soft findings (beliefs) in addition to hard findings (factual observations) among the organisations, each organisation’s analysis agent is capable of dynamically predicting its security risk level using a Bayesian network. A real-world implementation illustrates how our model can be used to manage security risks in distributed information systems and that sharing soft findings leads to lower expected loss from security risks.     

Technical efficiency and firm heterogeneity in stochastic frontier models: application to smallholder maize farms in Ethiopia

This study estimates the technical efficiency measures of maize producing farm households in Ethiopia using stochastic frontier (SF) panel models that take different approaches to model firm heterogeneity. The efficiency measures are found to vary depending on how the estimation model treats both unobserved and observed firm heterogeneity. Estimates from the ‘true’ random effects (TRE) models that treat firm effects as heterogeneity are found to be identical to those from pooled SF models. Those results differ from the ones generated from the basic random effects (RE) models that treat firm effects as part of overall technical inefficiency. The more flexible generalised ‘true’ random effects (GTRE) model that splits the error term into firm effects, persistent inefficiency, transient inefficiency, and a random noise component indicates the presence of higher levels of persistent inefficiency than transient inefficiency. The basic truncated-normal RE model and heteroscedastic RE model yields similar efficiency estimates. The GTRE model predict persistent efficiency measures similar to those from the basic RE and flexible RE model with environmental variables incorporated in the variance function as well as in the deterministic production frontier. These results imply that the RE and GTRE panel models provide reliable efficiency estimates for our data compared to the TRE models. All the estimated SF models generate comparable production function parameters in terms of magnitude and sign. Overall, the results underscore the importance of scrutinising stochastic frontier models for their reliability of analytical results before drawing policy inferences.

     

Inflationary equilibrium in a stochastic economy with independent agents

We prove the existence of stationary monetary equilibrium with inflation in a “Bewley” model with constant aggregate real variables but with idiosyncratic shocks to the endowments of a continuum of individual agents, when a central bank stands ready to borrow or lend fiat money at a fixed nominal rate of interest and the agents face borrowing constraints. We also find that, in the presence of real micro uncertainty about individual endowments, the rate of inflation is higher (equivalently, the real rate of interest is lower) than it would be in a “certainty-equivalent economy”; to wit, one in which every agent’s endowment is replaced by its expected value. Thus, underlying microeconomic uncertainty and borrowing constraints are shown to generate additional inflation.     

A road to assimilation: immigrants and financial markets

This paper compares the financial market participation of immigrants and native-born Americans. Financial asset ownership is examined after controlling for the immigrants’ country of origin using a nationally representative National Longitudinal Survey (NLSY79) data set. The determinants of preference for financial asset ownership and the amount of financial equity held by households are estimated using a two-stage procedure. The results indicate that immigrants are less likely to own financial assets and more likely to have lower financial equity than native-born residents. Income uncertainty and risk tolerance of immigrants are associated with their preference for financial investments. Immigrants’ years of residence in the United States also increase their financial asset ownership. A discussion of the implications of these findings for policy makers, immigration researchers, and scholars of household savings behavior is also included.     

A THEORETICAL APPROACH TO STERILIZED FOREIGN EXCHANGE INTERVENTION

In this paper, we survey prominent theories that have shaped the literature on sterilized foreign exchange interventions. We identify three main strands of literature: (1) that which deems interventions futile; (2) that which requires some market friction (i.e. limited arbitrage) in order for interventions to be effective; and (3) that which advocates the use of interventions as long as they convey signals on the stance of future monetary policy. We contribute to the literature in three important ways. First, by reviewing new theoretical models that have surfaced within the last decade. Second, by further penetrating into the theory of interventions in order to analyze the key features that make each model distinct. And third, by only focusing on sterilized operations, which allows us to sidestep the effects induced by changes in the stock of money supply. In addition, the models that we present comprise both a macro and microstructure approach so as to provide a comprehensive view of the theory behind exchange rate intervention.     

Limited participation in international business cycle models: A formal evaluation

In this paper, we argue that limited asset market participation (LAMP) plays an important role in explaining international business cycles. We show that when LAMP is introduced into an otherwise standard model of international business cycles, the performance of the model improves significantly, especially in matching cross-country correlations. To perform formal evaluation of the models we develop a novel statistical procedure that adapts the statistical framework of Vuong (1989) to DSGE models. Using this methodology, we show that the improvements brought out by LAMP are statistically significant, leading a model with LAMP to outperform a representative agent model. Furthermore, when LAMP is introduced, a model with complete markets is found to do as well as a model with no trade in financial assets – a well-known favorite in the literature. Our results remain robust to the inclusion of investment specific technology shocks.     

Economic policy and the presidential election cycle in stock returns

Many papers in the academic literature have documented a “Presidential Election” cycle in stock returns. Prior literature also documents that stock returns appear to be influenced by economic policy. The goal of this study is to examine the tools of fiscal and monetary policy to test for the presence of a presidential election cycle. The findings strongly suggest that the presidential election cycle in stock returns and the government’s economic policy influence on stock returns are two separate phenomena. Moreover, it is much more likely that stock returns are influencing economic policy rather than the other way around. However, the findings also suggest that tax legislation may drive the Presidential Election Cycle.     

Forward guidance – what does it mean and will it work?

The Bank of England has introduced ‘state‐contingent threshold guidance’, stating that it will not consider tightening monetary policy until the ILO unemployment rate has fallen below 7%. This is a similar policy to that adopted by the Fed in the US and represents an attempt to better manage the expectations of households, firms and financial markets about future changes in monetary policy.…
