Asymptotic inference in regression models with autoregressive errors having roots on the unit circle

An inference procedure is proposed for regression models with stationary regressors and non-stationary autoregressive errors. It is shown that the usual GLS or Cochrane–Orcutt procedure should be done in reverse order by starting the estimation from the error structure.     

Monetary policy in the BOF3 quarterly model of the Finnish economy

This paper describes the modelling of monetary policy in BOF3, a quarterly econometric model of Finland built at the Research Department of the Bank of Finland. BOF3 is a 198-equation, ‘amended Keynesian’ model which is used regularly in policy analysis and forecasting at the Bank. The modelling of the Finnish monetary sector has been complicated by the fact that most interest rates applied by the banks have so far been institutionally regulated. In spite of this, model builders have attempted to follow the conventional IS-LM approach as closely as possible, assuming that interest rates equilibrate financial markets outside the banking sector. The reported simulation experiments describe the effects of a change in nomical interest rates, of a change in the domestic money supply, and of a fiscal stimulus with and without monetary accomodation.     

Option to wait in a search model

We consider a standard search model with buyers and sellers. Upon meeting the buyers make a take-it-or-leave-it offer, but the sellers have an option not to trade immediately but wait for more agents to appear. If more buyers come, there is excess demand, and the buyers engage in auction to get the good. Analogously, if more sellers come, the sellers engage in a Bertrand-type pricing game to sell the object. The option to wait restricts the price offer of the buyer; in an equilibrium in which trades are consummated without delay there is a unique price offer for the buyer.JEL Classification: C78, D44, D831     

SEARCH DIRECTION AND WAGE DISPERSION*

In a directed search model, we allow the unemployed and the vacancies to choose whether to send or receive wage offers. This determines the market structure. There are several equilibria but a unique evolutionary stable one. Wage offers are made under incomplete information about the number of offers, and the equilibrium strategies involve mixing. This results in wage dispersion. We show that if the unemployment–vacancy ratio is close to unity, the stable equilibrium consists of two submarkets with opposite search directions. Otherwise, the long side of the market sends offers. The stable equilibrium is efficient, given the frictions.     

Book Reviews

This paper examines factors affecting the owner-manager's voluntary decision to hire an auditor in small firms. Using a random sample of 412 small private companies in Finland responding to an Internet survey, we first probe the institutional boundaries of a prior UK study [Collis, J., Jarvis, R., and Skerratt, L., 2004. The demand for the audit in small companies in the UK. Accounting and business research, 34 (2), 87–100] and conclude that its main findings can be generalised to a different regulatory setting (Finland) typical of many Continental European countries. Second, we broaden the prior research by testing new hypotheses regarding the drivers of an audit among small companies. We hypothesise and find evidence that outsourcing of critical accounting functions creates information asymmetry between the owner-manager and the external accountant, which may arouse the need for monitoring the external accountant through a voluntary audit. In addition, we find, as hypothesised, that tax advisory services provided by the external accountant reduce the likelihood of a voluntary audit. Moreover, we hypothesise that receiving a qualified opinion from the auditor reduces the likelihood of hiring an auditor voluntarily, whereas firms experiencing financial distress would be more willing to have their financial statements audited. We find evidence consistent with these hypotheses.     

Intertemporal efficiency analysis of sales teams of a bank: Stochastic semi-nonparametric approach

The primary role of a bank branch is evolving from a service provider towards a sales channel. Previous branch-level studies of sales efficiency consider a static setting of a single time period, ignoring the stochastic nature of sales outcomes. In this paper, we examine efficiency and performance of sales teams in a bank branch network over time, taking into account the changing demand and operational conditions, as well as random disturbances. The intertemporal sales frontier is estimated from the panel of monthly data over the years 2007–2010 using the stochastic semi-nonparametric envelopment of data (StoNED) method. The efficiency scores of sales teams and the trajectories of performance over time allow managers and the sales force to learn from past events and to develop the managerial and work practices across the network. While this study focuses on the case of a specific bank, some of the innovative features of our approach are applicable to sales efficiency assessment in other banks and financial institutions, as well as other network-based sales organizations.     

Stock market response to analysts' perceptions and earnings in a technology-intensive environment

This paper investigates the contemporaneous stock market response to financial analysts' perceptions of the firm and accounting earnings in the telecommunication and electronics industry in Finland. Analysts' perceptions used in the study are based on the Most Admired Companies survey similar to that conducted by Fortune magazine in the United States. The results indicate the nonfinancial information of the firm measured in terms of the analysts' perceptions has value relevance in a technology-oriented stock market.     

Promoting research access and informant rapport in corporate settings: Notes from research on a crisis company

Obtaining evidence on managerial action is inevitably difficult. Although it has been suggested that critical events such as corporate crises provide opportunities for research, there has been a lack of discussion on what aspects of management such conditions help to illuminate and how they could be exploited in obtaining both formal access and rapport with individual informants. Based on fieldwork experience this paper suggests that corporations in crisis should be taken seriously in research on managerial action because they may both facilitate access and liberate and motivate individual managers to reflect on both their own acts and intentions and on those of other individuals.     

Geographical focus in emerging markets and hedge fund performance

Emerging market hedge funds are an asset class which does not seem to outperform the market benchmarks. We hypothesize that the poor aggregate performance may be due to lack of focus of these funds. Our results suggest that a portfolio of emerging market hedge funds, which have geographical focuses, outperform their underlying stock markets. Hedge funds which focus on Eastern Europe appear to have the best outperformance. However, we also find that the performance of all emerging market hedge funds has reduced after the start of the 2008 Crisis.
