Portfolio Construction for Tests of Asset Pricing Models

Portfolios are commonly used in finance literature to study asset‐pricing models. In business practice portfolios are used to detect abnormal performance in certain asset groups or to construct reference assets. However, analyses on practical issues related to portfolio construction are surprisingly few. This paper presents and discusses issues related to portfolio return calculation from theoretical and practical perspectives. Special attention is given both to smaller and emerging stock markets. These stock markets often share common features like low liquidity, multiple stock series, and changes in foreign ownership restrictions that greatly affect portfolio construction.     

Communication as a determinant of organizational innovation

This study of 32 small and medium-sized industrial enterprises explored eight distinct aspects of communication, as appraised by the staff ( n  = 493), and innovative performance, assessed by two indicators: perceived innovation effectiveness and patent statistics obtained from the Patent Register at the National Board of Patents and Registration of Trademarks. The results showed that intra-organizational aspects of communication, such as encouragement of initiatives and critical evaluation of performance, were associated with both indicators of innovative performance. In addition, a participative climate and interaction between the personnel in R&D, marketing and production were related to perceived innovative effectiveness, whereas interaction with clients and other firms related to the number of patents in the organization. The link between communication and innovation was interdependent with the organizational and staff characteristics including the number of personnel, administrative and R&D intensity, the level of vocational training, and the age distribution of the staff.     

EU-Enlargement and Beyond: A Simulation Study on EU and Russia Integration

This paper examines the economic effects of the opening of the Russian Federation. The analysis carried out in the paper is twofold. First we simulate the impact of the eastern enlargement of the EU and, second, we analyse how deeper integration between the EU and Russia contributes to this. The analysis is carried out with GTAP, a computable general equilibrium model. We find that there is a trade-off between the two roads of European integration arrangements. Eastern enlargement seems, even in its very deep form, be beneficial for all EU regions without causing substantial welfare losses outside the Union. EU–Russia integration, on the other hand, has different impact. To be beneficial for Russia free trade between the EU and Russia requires improved productivity in the latter, which may be due to better institutions or increased FDI. This might make the negotiations of the agreement cumbersome and if agreed its implementation difficult.This study stems from a project Opening of Russia in which the authors participated at RECEP in Moscow.

The globalization strategies of business-to-business born global firms in the wireless technology industry

This paper discusses the globalization process of business-to-business born globals in a rapidly growing industry, the wireless technology industry. Deviations in these patterns in regards to the mainstream pattern of internationalization and earlier born global literature are discussed. Furthermore, the roles of the founders and managers, the networks, the financial resources of the companies, and the innovations behind the companies under consideration are analyzed. A conceptual framework and propositions explaining the product, operation and market strategies of born globals are developed. The results suggest that born globals in the wireless sector do in fact deviate from the traditional internationalization process in many areas. Their expansion even to distant markets is rapid and they apply advanced product strategies at an early stage. However, their business operations are found to proceed at a more conventional pace and the notable difference from traditional firms is the rapid establishment of sales and marketing subsidiaries. Results emphasize the key role of the resources and capabilities of born globals in influencing the advancement of product categories, operation strategies, and global market presence. Born global firms were found to lack the resources and capabilities accumulated by traditionally internationalizing firms, and they therefore need to acquire them either through the earlier experience of the founding team, which should be complementary in nature, or from external domestic and international network actors.     

Globalization and marketing strategies of Born Globals in SMOPECs

This research examines Born Global companies, which are facing tremendous entrepreneurial and managerial challenges related to instant or rapid globalization. A major research problem addressed is whether the strategies and processes of Born Globals differ essentially from those of other firms in respect to globalization and global marketing. Based on a literature analysis, we first examine the concept of Born Globals and then turn to a review of the research dealing with the globalization and marketing strategies of Born Globals. Survey results on 89 Finnish Born Globals from high‐tech, high‐design, high‐service, high‐know‐how, and high‐system business areas are presented. Their domestic stage lasts for an average of only 2.1 years. For conventional companies, the period is ten times longer. Furthermore, Born Globals can be classified on the basis of their development into three preliminary stages (research & development [RD], domestic, and entry) and into four major stages (starting, development, growth, and mature). The study then proceeds to examine the globalization and global marketing strategies of Born Globals through a multiple case study of 30 case companies representing the above development stages. Special attention is paid to the mature Born Globals, which were found to have passed quickly through the conventional internationalization stages, jumped over some stages, and, in some cases, even progressed in reverse order. After this, attention turns to a detailed examination of the challenges identified and their solutions for three particular interest groups: entrepreneurs, government policymakers, and academicians. The implications of the results for entrepreneurs should be of particular importance, as managerial, research and development, sales and marketing, and also financial challenges and solutions are covered in detail. Finally, this research concludes that although many of the Born Global findings deviate from the internationalization behavior of conventional companies, the holistic and company‐level stage models still seem to have a high degree of explanatory power for many companies originating in small and open economies (SMOPEC). © 2006 Wiley Periodicals, Inc.     

Trading firms in the services sectors: comparable evidence from four EU countries

We establish a set of stylised facts for trade and trading firms in five market services sectors using comparable firm- and activity-level data from four EU countries. Our analysis shows that exports account for much lower shares of overall sales in the services sectors than in manufacturing. This is because fewer firms are engaged in trade in the services sectors and also because within particular sectors firms trade a lower share of their sales on average. Services producers trade mostly goods, but in terms of value, trade in services is much more important to them than to manufacturers. Larger and more productive firms are more likely to be two-way traders and to engage in both goods and services trade. Trade by services firms is somewhat less dominated by firms that both export and import than trade by manufacturing firms. Few firms export many services or to many countries. The value of services exports is increasing in the number of markets served but not necessarily in the number of services traded.     

The role of business subsidies in job creation of start-ups, gazelles and incumbents

This study contributes to the empirical literature concerning the role of business subsidies in job creation. Our empirical analysis, using an extensive firm-level data, suggests that the impact of business subsidies on employment growth differs more between high-growth start-ups and other firms than between start-ups and incumbents. On average, all subsidies relate positively to the contemporary employment growth for both start-ups and incumbents. Furthermore, after subsidy reception, the employment of both start-ups and older incumbents receiving employment or other subsidies grows more than that of non-subsidized firms. However, we find that business subsidies do not provide a significant additional boost to either contemporary or after-subsidy growth for young high-growth companies. There are apparently some other factors that promote growth in young high-growth firms; these factors help foster strong growth in many cases with or without subsidies.     

Informational mobility and productivity: Finnish evidence

The labor productivity effects of portability and connectivity of information and communication technology (ICT) are studied with Finnish firm-level data. It is found that a computer with only processing and storage capabilities boosts labor productivity by 9% (corresponding to 5% output elasticity), portability by 32%, wireline connectivity by 14%, and wireless connectivity by 6%. The findings are in line with previous literature and comparisons to ICT costs suggest that firms equate marginal costs and returns. Although increasing ICT penetration can no longer be a major source of productivity growth in developed economies, the relatively new characteristics studied can.     

Do Urban Neighborhoods Benefit from Homeowners? Evidence from Housing Prices

Homeownership is heavily subsidized in most countries. The adverse effects of this policy on economic efficiency and income distribution are well documented in the economics literature. The main argument in favor of subsidizing homeownership is that it creates positive externalities that offset these adverse effects. In this paper, we test whether homeowners create positive externalities that capitalize into housing prices in multi‐storey buildings. Using semi‐parametric hedonic regressions with and without instrumental variables, we find no evidence of positive externalities, although the results with instrumental variables are somewhat imprecise. This result is robust to several sensitivity checks and to a relaxation of the identification assumptions of our instrument using set identification.     

Born globals: Propositions to help advance the theory

Although born globals (BGs) have now been studied for over a decade, theory and practice are still evolving. This article was written to clarify the definition of a Born Global (BG) firm and to describe the three phases—introductory, growth and resource accumulation, and break-out to independent growth as a major player—through which BGs progress. Drawing from empirical evidence, it was found that the risks, resource development, channels/networks and organisational learning of BGs develop during the three phases through which successful BGs pass. However, this process deviates considerably from that followed by traditional internationalising small- and medium-sized enterprises (SMEs). Born Global entrepreneurs and academics can learn much by studying the causes of these differences.
