ECB Monetary Policy Surprises: Identification Through Cojumps in Interest Rates

This paper proposes a new econometric approach to disentangle two distinct response patterns of the yield curve to monetary policy announcements. Based on cojumps in intraday tick data of short‐ and long‐term interest rate futures, we develop a day‐wise test that detects the occurrence of a significant policy surprise and identifies the market perceived source of the surprise. The new test is applied to 133 policy announcements of the European Central Bank (ECB) in the period from 2001 to 2012. Our main findings indicate a good predictability of ECB policy decisions and remarkably stable perceptions about the ECB's policy preferences. Copyright © 2015 John Wiley & Sons, Ltd.     

The development of models of accounting information systems in Sweden

Traditionally, accounting has evolved as a technique. Practitioners and academics have striven to improve the technical features of accounting. Now, accounting is conceived increasingly as an organizational artefact which interacts with other organizational practices in shaping organizational reality. Taking a broad perspective of management control, this paper aims at contributing to our knowledge of accounting in this second sense and identifying some Swedish contributions to the tool-box of accounting. In reviewing the development of models of accounting information in Sweden mainly since World War II, different factors explaining the evolution of each model are identified. Analyses of these factors reveal that different groups of actors have been engaged in the development of different parts of the accounting information system (AIS). It is also noted that the introduction of models that are widely applied has delayed the emergence of new models better adapted to the current situation in business. Comparisons will be made with the development in some other countries.     

Estimation of commodity-by-commodity input–output matrices

In this paper we derive a method for the estimation of symmetric input–output tables (SIOTs), which makes it possible to use the commodity technology assumption even when use- and make tables are rectangular. The method also solves the problem of negative coefficients. In the empirical part we derive annual SIOTs in order to evaluate the differences between SIOTs calculated with different methods and the change in technical coefficients over time. Our results, based on data for Sweden, show that the impact of using different technology assumptions is rather large. However, in a factor content of trade application the impact of different technology assumptions does not seem to be very important. Also the size of the changes in the technical coefficients over time is found to be quite large, indicating the importance of calculating SIOTs annually.     

User Toolkits for Innovation: Consumers Support Each Other

User toolkits for innovation were recently proposed as a means to eliminate (costly) exchange of need-related information between users and manufactures in the product development process. The method transfers certain development tasks to users and thereby empowers them to create their own desired product features. This article examines the implications of different levels of opportunities for consumer involvement (OCI) in product development to learn what happens when firms pass design tasks on to consumers. It explores this issue by studying the relation between the employment of user toolkits and the need for firms to support their consumers. An analysis of 78 computer games products and the amount of support given by firms to the consumers of these products suggests that a share of the costs firms save on information acquisition by letting consumers "do it themselves" may eventually reemerge as costs in consumer support. In other words, an increase in opportunities for consumer involvement seems to increase the need for supporting consumers. A promising solution to the problem of support costs is identified, namely, the establishment of consumer–consumer support interaction. A case study of an outlier in terms of firm support to consumers—Westwood Studios—shows that consumers who use toolkits may be willing to support each other. Such interactive problem solving in a firm-established user community is advantageous to the firm, because the process reduces the amount of resources that the firm itself needs to dedicate to the support of consumers using toolkits. Generally, consumer-to-consumer interaction can facilitate problem-solving in the consumer domain, can aid the diffusion of toolkit related knowledge, and potentially can enhance the outcomes produced by the toolkit approach.     

Design of economic information. A pilot study of accounting information in decision-making processes

Accounting information is developed for an analytic decision-making process, whereas many farmers use an intuitive process. The aim is to determine the decisions and parts of the decision-making that farmers use for accounting information, and to what extent accounting information would be more useful if it was designed to fit the decision-making process used. A limited sample of milk-producing farmers in Uppsala County, Sweden, was studied. For detecting scale problems, the values of the financial statement were of primary importance and the design of the profit and loss statement was of secondary importance. For detecting efficiency problems, the values of the profit and loss statement were most important, the content of the commentary information was the second most important, and the design of the financial statement was the third most important. Farmers using an intuitive decision-making process perceived problem detection to be easier if the information was designed to fit the intuitive process. However, farmers using an analytic decision-making process did not perceive problem detection to be easier if the accounting information was designed to fit the analytic process. Also they valued the information designed for the intuitive process.     

Cost Accounting and Performance Measurement in a Just-in-Time Production Environment

There are normative statements in the literature, backed up by case observations and anecdotal evidence, which indicate that manufacturing companies operating just-in-time (JIT) production management systems should also change their cost accounting systems and place greater reliance on non-financial performance indicators. This study provides empirical evidence suggesting that JIT manufacturing companies which have made some degree of modification to their costing system demonstrate higher performance than JIT companies which have not made changes. The results also suggest that greater use of non-financial performance indicators is associated with higher performance irrespective of the production management system adopted.     

Cooperation or competition in R&D when innovation and absorption are costly

This article analyzes cost-reducing R&D investments by firms that behave non-cooperatively or cooperatively. Firms face a trade-off between allocating their R&D investments to innovate or to imitate (absorb). We find that the non-cooperative behavior not only induces more imitation (absorption) but also, for the most part, more innovation investments. Only the cooperative behavior, however, ensures that R&D investments are allocated efficiently to innovation and to imitation (absorption) in the sense that any given amount of industry-wide cost reduction is obtained for the minimum overall R&D costs.     

Limits to arbitrage and hedging: Evidence from commodity markets

We build an equilibrium model of commodity markets in which speculators are capital constrained, and commodity producers have hedging demands for commodity futures. Increases in producers' hedging demand or speculators' capital constraints increase hedging costs via price-pressure on futures. These in turn affect producers' equilibrium hedging and supply decision inducing a link between a financial friction in the futures market and the commodity spot prices. Consistent with the model, measures of producers' propensity to hedge forecasts futures returns and spot prices in oil and gas market data from 1979 to 2010. The component of the commodity futures risk premium associated with producer hedging demand rises when speculative activity reduces. We conclude that limits to financial arbitrage generate limits to hedging by producers, and affect equilibrium commodity supply and prices.
