Market efficiency broadcasted live: ECB code words and euro exchange rates

This paper examines the impact of the European Central Bank (ECB) monetary policy on euro exchange rate returns using an event study with intraday data for five currencies (the euro exchange rate versus the US dollar, the British pound, the Canadian dollar, the Swiss franc, and the Japanese yen). I construct two indicators of news about monetary policy stemming separately from policy decisions and the press conference. Estimation results show that the surprise component of communication has highly statistically significant effects on exchange rates, whereas the response of euro exchange rates to the unanticipated change in the policy rate is more muted. I also estimate the financial market impact on euro exchange rates of US, European and German macroeconomic news, and I show that the impact of the ECB press conference is economically important. The process of fully incorporating the ECB news shock takes about 1 h, and thus this result suggests that the whole press conference (both the Introductory Statement and the Q&A part) provides valuable information to market participants.     

Search for financial returns and social security privatization

I develop a general equilibrium model in which the quality of household financial decisions is endogenously determined by the incentives to exert effort in learning about financial opportunities. The model generates predictions for asset market participation and returns across households. Moreover, search for financial returns enables the model to generate a more skewed equilibrium wealth distribution. In this context, social security privatization affects household search effort, asset market participation and the competitiveness of the asset market. Privatization reduces average welfare and this reduction is somewhat magnified by the search friction. While some have suggested that household decision making could be important for the consequences of privatization, my analysis does not bear this out.     

中国房地产市场的地域特征分析

建立在全国性市场假设基础之上的关于我国房地产业市场集中度较"低"和"过度竞争"的推断,忽视了其本地性。事实上,由于房地产市场的本地特征,不同"板块"间相互分离。房地产企业只是与"板块"内相邻的企业发生竞争,即便是这样,它们也还都有其各自的垄断市场区;加之房地产业存在较高的进入壁垒,垄断性较强,房地产企业拥有着较强的市场力量①。     

Bargaining with asymmetric information in non-stationary markets

Summary. The Rubinstein and Wolinsky bargaining-in-markets framework is modified by the introduction of asymmetric information and non-stationarity. Non-stationarity is introduced in the form of an arbitrary stochastic Markov process which captures the dynamics of market entry and pairwise matching. A new technique is used for establishing existence and characterizing the unique outcome of a non-stationary market equilibrium. The impact of market supply and demand on bilateral bargaining outcomes and matching probabilities is explored. The results are useful for examining such questions as why coordination failures and macroeconomic output fluctuations are correlated with real and monetary shocks.

Economic uncertainty in South Africa

The idea that heightened uncertainty among firms contributed to the Great Recession and the lacklustre subsequent recovery has inspired a substantial literature examining the impact of changes in uncertainty on output and investment decisions. Yet to date there has been little research on business uncertainty in emerging markets. This paper is one of the first to develop a set of survey-based proxies for business uncertainty for an emerging market, South Africa, based on micro-data from business tendency surveys. These survey-based proxies are combined with more common measures of uncertainty, based on financial data and text mining, to obtain a composite measure of economic uncertainty. The paper then examines whether the uncertainty indicators have plausible and significant relationships with real economic activity, even after controlling for other economic variables. The indicators exhibit a significant negative correlation with real GDP growth, consistent with the findings for developed countries, and a positive shock to uncertainty is generally followed by a significant decrease in real activity growth.     

Wage transparency and performance: A real-effort experiment

Without transparency about peer wages in a real effort experiment, a change of wages does not affect performance. With transparency, however, higher paid workers tend to work more accurately, and lower paid workers shirk more under piece rates.     

资本市场对外开放能够促进企业创新吗?——基于“沪港通”交易制度的经验证据

作为资本市场对外开放的改革创新机制,沪港通交易制度的实施吸引了众多学者的关注。但现有研究主要考察了沪港通交易制度对资本市场信息效率的影响,对其是否会影响微观企业行为,尤其是企业的创新投资行为研究不足。基于此,本文采用2010—2016年A股上市公司为样本,利用沪港通交易制度实施这一事件作为准自然实验,构建双重差分模型,实证检验了沪港通交易制度对企业创新的影响。研究发现:(1)沪港通交易制度实施后,沪股通标的企业的创新水平显著上升。(2)经理人职业忧虑在沪港通交易制度影响企业创新的过程中既发挥了中介作用,又具有调节效应。表明缓解经理人职业忧虑,抑制经理人短视行为是沪港通交易制度促进企业创新的重要途径。(3)沪港通交易制度对企业创新的促进作用受到上市公司信息环境的调节影响,二者之间的正向关系在上市公司信息环境较差时更加强烈。本研究为沪港通交易制度影响微观企业行为的研究提供了新的实证证据,并揭示了沪港通交易制度影响企业创新的作用机制,对于深刻理解沪港通交易制度,持续推进资本市场对外开放进程,提高企业创新能力,实现创新驱动发展战略,具有重要的启示意义。     

The London Business School econometric model of the UK

This paper describes the London Business School econometric model — the first fully computerized model of the UK — which has been used for regular public forecasting since 1966. The model, estimated on quarterly data, is organized around the income expenditure accounts with a fully integrated flow of funds sector which ensures consistency between portfolio decisions and income, savings and investment decisions. Aggregate demand is built up from its individual components so that demand influences are important for the short- and medium-term behaviour of the model. But there are important supply-side effects which work through the real exchange rate and real wages. Monetary conditions have a powerfull effect on the model through the exchange rate, personal sector wealth and interest rates. Wages and employment are determined in a labour market in which employment decisions depend on the level of demand and real wages while real wages depend on the level of unemployment, real benefits and direct and indirect taxes as well as underlying trends in productivity. Asset prices move in any period to clear both the spot and the future market in assets so that current asset prices in the equity, gilt-edged and foreign exchange markets reflect all current information about the expected state of the economy. In contrast, goods prices adjust sluggishly. The combination of continuously clearing asset markets and sluggish wages and prices gives the model many of the theoretical characteristics associated with the open-economy models of Dornbusch and Buiter and Miller.     

Real-time forecasts of economic activity for Latin American economies

Macroeconomic policy decisions in real-time are based on the assessment of current and future economic conditions. Crucially, these assessments are made difficult by the presence of incomplete and noisy data. The problem is more acute for emerging market economies, where most economic data are released infrequently with a (sometimes substantial) lag. This paper evaluates nowcasts and forecasts of real GDP growth using five models for ten Latin American countries. The results indicate the flow of monthly data helps to improve forecast accuracy, and the dynamic factor model consistently produces more accurate nowcasts and forecasts relative to other model specifications, across most of the countries we consider.     

Real capital market integration in the EU: How far has it gone? What will the effect of the euro be?

Much effort has been devoted to the study of financial market integration in Europe. Little is known, however, about real capital market integration – the degree to which plants and equipment move to take advantage of locally high returns. This paper looks at the evidence. An analysis of flows of foreign direct investment in Europe shows that integration was quite limited in the early 1980s, but has increased considerably since then. Another analysis looks at rates of return of a large number of firms. It reveals that country-specific factors play a significant role in explaining corporate returns, even after taking risk into account. This finding is incompatible with the CAPM definition of market integration. The view that integration is limited in Europe is further strengthened when the same approach is carried out for the USA and Canada. Part of the national specificity appears to be related to labour and goods market regulations, which harm firms profitability. If, by introducing more transparency and eliminating currency risk, EMU strengthens competition on the real capital market, one obvious economic benefit will be a more rational and efficient use of capital, but the most important potential consequences are political. Special-interest regulations of an exclusively national nature will not survive. They will either fall in a wave of internationalist liberalization, or become embedded in 'harmonized' regulations at the federal level. A reduction in excessive regulatory burdens, notably in the labour market, could lead to substantial and shared productivity gains.     

Competition among banks and the pass-through of monetary policy

This paper introduces monopolistically competitive financial intermediaries into the New Keynesian DSGE setting. Modelling bank market power explicitly contributes to understanding two empirical facts: (i) The short-run transmission of changes in money market rates to bank retail rates is far from complete and heterogeneous. (ii) Stiffer competition among commercial banks implies that loan rates correlate more tightly with the policy rate. In my model, the degree of monopolistic competition in the banking sector has a sizeable impact on the pass-through of changes in the policy rate. In particular, a more competitive market for bank credit amplifies the efficiency of monetary policy.

Government payments,market profits and structural change in agriculture

I analyze the interaction of two institutions, markets and public policies, and their effect on structural change in agriculture. More specifically, I consider how subsidies affect functioning of input and output markets, and the selection of business strategies within them. The main hypothesis is that subsidies affect these markets differently, and that allows rent-seeking that hinders the overall productivity of the sector. I apply a replicator dynamics model for the task. I test my hypothesis with the EU’s 2003 CAP reform. The data is comprehensive microdata of Finnish grain and oilseed farms for years the 2004–2013. In order to examine distributional level shifts, I use quantile regression techniques. I find that the policy incentives have directed sectoral change more strongly than market incentives and have thus significantly affected production decisions. The subsidies have also attenuated the market signals and therefore increased sectoral inefficiency. The reform that aimed to improve market orientation has had little effect. The reform has affected structural change in input and output markets differently. While land use adjustment has become more rigid for all the farms, especially the more market oriented ones have been able to exploit increased output market flexibility. However, the negative effects are more prominent in total and the net effect of the reform was negative.     

Currency Exposure to Downside Risk: Which Fundamentals Matter?

I study whether or not countries' macroeconomic characteristics are systematically related to their currencies' exposure to the downside market risk. I find that the currency downside risk is strongly associated with the local inflation rate, real interest rate and net foreign asset position. Currencies of countries with high inflation and real interest rates and negative net foreign asset position (debtor countries) are more exposed to the downside risk whereas currencies of countries with low inflation and real interest rates and positive net foreign asset position (creditor countries) exhibit “safe haven” properties. The local real interest rate has the highest explanatory power in accounting for the cross‐section of currency exposure to the downside risk. This suggests that the high currency exposure to the downside risk is a consequence of investments in high‐yield risky countries and flight from them in “hard times”.     

Basic income and the labour market: Labour supply,precarious work and technological change

In this paper, I examine the relationship between a basic income as a policy tool and the functioning of the labour market. I focus on three key areas where a basic income has been hypothesized to relate to labour markets: (i) through altering work decisions, (ii) as a response to predicted changes in work arising from technological change and (iii) as backstop that would allow workers to demand better working conditions and higher wages. I provide answers on the role or impact of a basic income in each area in the context of the current Canadian labour market. But a key focus in the paper is on the ways we could alter our labour market models to provide a better basis for debating the impacts of policies like a basic income in the context of a goal of moving toward a more just society.     

The effect of heterogeneous beliefs on mergers and acquisitions

This article investigates the effect of heterogeneous beliefs on firms’ mergers and acquisitions (M&A) decisions. Using data of China’s financial market, which is featured with great heterogeneity of belief, we find that heterogeneous beliefs are positively associated with the occurrence of M&A transactions, and firms with greater heterogeneous beliefs are more likely to pay the transactions with stock. Moreover, we show that government intervention, measured by state ownership, weakens the effect of heterogeneous beliefs on firms’ M&A decisions.     

Occupational self-selection in a labor market with moral hazard

This paper studies the determinants and implications of self-selection when firms imperfectly observe worker effort. The effects of the resulting moral hazard problem on the self-selection mechanism are analyzed in a model in which workers simultaneously choose an employment sector and an effort level. The implications of the model reveal that in the presence of moral hazard, workers’ effort decisions become an additional mechanism determining the pattern of selection into sectors. Workers’ sector-specific endowments impact sectoral allocation through their effect on workers’ comparative advantage as well as their effect on workers’ shirking propensity. The model is then used in an empirical application that analyzes workers’ self-selection into white collar and blue collar occupations. The estimation results, based on data from the National Longitudinal Survey of Youth, suggest that workers’ occupational self-selection leads to higher wages and lower dismissal rates in both occupations, compared to an economy in which workers are randomly assigned to each occupation. The difference in dismissal rates between the two occupations is driven by the higher expected productivity in the white collar sector. The positive effects of occupational sorting diminish as the labor market becomes increasingly characterized by moral hazard. Results also suggest that human capital investments in skills that are most relevant to blue collar jobs may generate higher wages and lower dismissal rates in both white collar and blue collar occupations.     

The effects of competitors on new product launch and market expansion in the hybrid car market

This paper evaluates the effect of competitors on automakers’ new product launch and market expansion decisions in the hybrid car market. Using data from the entire history in US hybrid car market from 2000 to 2014, this paper estimates a Poisson model with endogeneous switching to account for the initial launch and the following expansion decisions. The results indicate that the presence of competing brands’ hybrid vehicle models has a net positive effect on a brand’s initial launch and expansion decisions. This suggests that demand expansion and market learning from competitors’ hybrid model launch and consumer cultivation are very important for this relatively new technology. Further, I find that the impact of competitors varies over time, vehicle origins, and classes.
