Forecasting ECB monetary policy: Accuracy is a matter of geography

Monetary policy in the euro area is conducted within a multi-country, multi-cultural, and multi-lingual context. How does this heterogeneity affect the ability of economic agents to understand and to anticipate monetary policy by the European Central Bank (ECB)? Using a database of surveys of professional ECB policy forecasters in 24 countries, we find remarkable differences in forecast accuracy, and show that these have important repercussions on market behaviour. Explaining the differences in forecast accuracy, we provide evidence that they are partly related to geography and clustering around informational hubs, as well as to country-specific economic conditions. In large part this heterogeneity can be traced to differences in forecasting models.     

A test of trade theories when expenditure is home biased

We develop a criterion to distinguish two dominant paradigms of international trade theory: homogeneous-goods perfectly competitive models, and differentiated-goods monopolistically competitive models. Our analysis makes use of the pervasive presence of home-biased expenditure. It predicts that countries’ relative output and their relative home biases are positively correlated in differentiated-goods sectors (the “home-bias effect”), while no such relationship exists in homogeneous-goods sectors. This discriminating criterion turns out to be robust to a number of generalisations of the baseline model. Our empirical results, based on a world-wide cross-country data set, suggest that the differentiated-goods model fits particularly well for the machinery, precision engineering and transport equipment industries, which account for some 40% of sample manufacturing output.     

Modeling national flood insurance policy holding at the county scale in Florida, 1999-2005

We analyze household flood insurance purchases in Florida from 1999 to 2005, and the extent to which household insurance purchases correspond with flood mitigation activities by local governments involved in the Federal Emergency Management Agency's (FEMA) Community Rating System (CRS). Regression results indicate that household flood insurance purchases correlate strongly with local government mitigation activities, adjusting for hazard experience, hazard proximity, and community demography. Policy implications of this observed relationship are discussed, assuming four temporal order and floodplain development scenarios, with particular attention to the congruence of outcomes relative to policy objectives.     

Systemic risk contagion in FX market: A frequency connectedness and network analysis

In this study, we analyse systemic risk contagion between a set of most actively traded currencies (EURO, JPY, GBP, AUD, CAD and CHF) by application of VAR based frequency connectedness proposed by Baruník and K?ehlík. By using this novel approach, we gauge foreign exchange (FX) market connectedness in 200‐day frequency band using spectral representation of variance decompositions of VAR and identify directional spillovers between the most actively traded foreign exchange rates. Dynamics of the overall spillover index reveals that the index capture well‐known financial stress incidents properly. Finally, network topology of directional spillovers between currency pairs is provided for visulalization interconnectedness between them.     

高新技术企业认定对企业全要素生产率的影响——基于双重差分方法的分析

基于2002—2018年中国A股上市公司面板数据,运用双重差分方法考察高新技术企业认定对企业全要素生产率的影响及机制。结果表明,高新技术企业认定显著促进相关企业全要素生产率提高,对企业高质量发展具有积极效应。机制检验结果显示,高新技术企业认定促进企业研发投入规模扩大和资本配置效率改善,进而有利于全要素生产率提升。进一步异质性检验结果表明,这种效应在高融资约束企业、处于成长成熟期企业和未进行研发操纵企业中更显著。此外,外部环境对政策实施效果具有重要影响。相关结论可以为高企认定政策效果评价提供新的研究视角,为我国完善选择性产业政策设计提供政策启示。     

The time-varying policy neutral rate in real-time: A predictor for future inflation?

This paper examines the time-varying policy neutral interest rate in real-time for the Czech Republic in 2001:1–2006:09, estimating various specifications of simple Taylor-type monetary policy rules. For this reason, we apply a structural time-varying parameter model with endogenous regressors. The results indicate that the policy neutral rate gradually decreased over the sample period to levels comparable to those in the euro area. Next, we propose a measure of the monetary policy stance based on the difference between the actual interest rate and the estimated policy neutral rate and find it a useful predictor of the level as well as the change of the future inflation rate.     

Transparency in monetary policy: A general equilibrium approach

We study a general equilibrium model with a central bank (CB) and two groups of agents, producers and workers. The CB maximizes a weighted average of utilities of the two groups. The CB has two possible types, one favoring workers and the other favoring producers. The CB's type is private information. We compare two possible monetary policy regimes, transparent and opaque. For realistic values of parameters, it is shown that workers are better off under the opaque regime, whereas producers are better off under the transparent regime. This result is shown to hold in two cases, when the range of possible monetary transfers is small and when the range of possible monetary transfers is large.     

The effects of federal regulations on corruption in U.S. States

Using the newly constructed Federal Regulation and State Enterprise Index (FRASE Index) to measure the federal regulations and the existing Corruption Convictions Index (CCI), we investigate the effects of federal regulations on corruption in U.S. states. Controlling for several demographic and economic variables including the Fraser Institute’s Economic Freedom Index (EFI), which measures the size and scope of government in U.S. states, we find a positive and statistically significant relationship between federal regulations and corruption. Our findings have important policy implications. A 1 standard deviation increase in FRASE Index causes CCI to increase by approximately 0.5 standard deviations. Standardized coefficient of EFI is also approximately equal to 0.5. In other words, it is possible to mitigate the effects of regulations at the federal level by reducing the size and the scope of the government at the state level.     

Financial frictions and the futures pricing puzzle

In perfect capital markets, the futures price of an asset should be an unbiased forecast of its realized spot price when the contract matures. In reality, futures prices are often higher for some assets and lower for others. However, there is no stability in the relationship between futures prices and the realized spot prices. This instability has been a puzzle in the existing financial literature. The key to this puzzle may lie in the nature of the model and the lack of market imperfections. In this study, we take a theoretical approach in a dynamic multi-period environment. We incorporate competition between disparate economic agents and impose financial frictions (i.e., imperfections) that are in the form of hedging and borrowing limits on them. Our model gives rise to multiple equilibria, each with unique market clearing prices, with the market switching between these equilibria. Our analysis incorporates a comprehensive consideration of the risks faced by the futures markets participants (i.e., speculators and hedgers) and leads to a better understanding of the puzzle.     

Wage rigidities and unemployment fluctuations in a small open economy

This study analyzes the implications of the monetary policy for the unemployment rate in a small open economy. We introduce nominal wage rigidities and unemployment into the small open economy version of the dynamic stochastic general equilibrium model. We derive three main findings. First, under nominal wage rigidities, the cyclical properties of the calibrated model, in response to a productivity shock, are consistent with the empirical evidence on a decrease in employment and an increase in real wages. Second, for all the variables considered, the Taylor rule tracks the optimal policy better than the simple rule with unemployment as an argument. Third, regardless of the output or unemployment gap being targeted, it is not optimal that central banks respond to nominal exchange rate variations.
