Digital assemblages: evidence and theorising from the computerisation of the US residential real estate industry

We develop the concept of digital assemblages in order to advance current theorising on the ways in which information and communication technologies (ICTs) are helping to reshape work. The empirical setting is the US residential real estate industry—a ‘living laboratory’ for studying information‐intensive work and the adoption and uses of ICT. We find that real estate agents' uses of ICT are pervasive and suggest that agents now embed themselves more deeply into the transacting of real estate by actively supporting buyers and sellers, rather than acting primarily as information intermediaries. Building from this, we theorise that this ICT use can more coherently be understood as a ‘digital assemblage’ rather than a formal information system. Digital assemblages are characterised as distinct patterns of ICT collections that, in use, are functionally equivalent and structurally similar, relying on standardised and commodified ICT and are neither formally designed nor collectively governed.     

Evaluating internal and external knowledge sources in firm innovation and productivity: an industry perspective

Both internal knowledge – investment in internal R&D and information and communication technologies (ICT) as well as external knowledge – knowledge spillovers and active collaboration with partners are rapidly fostering firm productivity and innovation. In this study, we investigate the role of internal and external knowledge in firm productivity and innovation. In addition, we test interactions between investment in R&D and ICT as well as between knowledge spillovers and knowledge collaboration in their association to firm innovation and productivity. We use a recombinant innovation approach and four samples for firms in manufacturing, creative, ICT and science, and professional services industries during 2002–2014 and for pre-and post-crisis periods to perform our analysis. In addition to innovation and productivity, we also examine the role of internal and external knowledge as a conduit to the development of innovation internally and the co-creation of innovation with external partners. Our results lead to managerial and policy implications.     

Total factor productivity enablers in the ICT industry: A cross-country firm-level analysis

Advancements in productivity in the digital economy constitute an important engine for economic growth. What drives productivity dynamics in the information and communication technology (ICT) sector? This study examines the productivity dynamics of ICT firms across countries from the perspective of corporate balance sheets. We study the effects of intangible assets and leverage on productivity growth using firm-level panel data from five industrialized countries. We find that intangible assets positively affect the total factor productivity in the ICT sector. The positive effect of intangible assets on total factor productivity growth is larger for ICT manufacturing firms than for ICT service firms. We also find that leverage has a positive relationship with total factor productivity development in the ICT sector. In addition, our empirical results substantiated that productivity is catching up to the technological frontier. Furthermore, larger firms and/or younger firms generally show higher total factor productivity growth than their peers. Economies of scale are more prominent in the ICT service sector than in the ICT manufacturing sector. Our findings contribute to the understanding of cross-country productivity dynamics in the ICT sector at the firm level in the digital economy.     

Measuring efficiency and ICT ecosystem impact: Hardware vs. software industry

The ICT industry is reshaping itself through convergence and coopetition across the ecosystem. In particular, many ICT companies have been trying to achieve both hardware and software capabilities to accelerate innovation. To understand the changes in the ICT industry, we empirically study the hardware and software industries using the ecosystem framework. We estimate the efficiency levels of the hardware and software industries in China, Japan, South Korea, and the United States (US) using stochastic frontier analysis and meta frontier analysis, and we examine the effects of the ICT ecosystem structure on efficiency levels using a Tobit regression. We find that the US, which is the global ICT leader, performs significantly better than other countries, with the biggest technology gap ratios in both hardware and software, and South Korea, which has the most hardware-centric industrial structure among the four countries, has the biggest efficiency gap between the hardware and software industries. Tobit results further reveal that a well-balanced ecosystem is important in achieving high efficiency in both hardware and software, and the effect is much higher in the software industry than in the hardware industry.

ICT investment-specific technological change and productivity growth in Korea: Comparison of 1996–2005 and 2006–2015

This paper analyses the impact of information and communications technology (ICT) on the productivity growth in Korea with the dynamic general equilibrium (DGE) model including investment-specific technological change. According to the balanced growth path analysis, ICT investment-specific technological change accounts for 18.8% to labor productivity growth in 1995–2005, then 14.3% in 2006–2015, and the decline in the rate of ICT investment-specific technological change has contributed to the slow productivity growth since the mid-2000s. In cyclical fluctuations, ICT investment-specific technological shocks were significant in output variance in 1996–2005, but neutral technological shocks and non-ICT investment specific shocks became dominant in 2006–2015. In sum, it can be concluded that the impacts of ICT investment-specific technology have diminished in the growth path and cyclical fluctuations. The result that increased (decreased) ICT investment intensity with faster (slower) ICT investment-specific technological change lead to higher (lower) productivity growth indicates that Korea has been a case against the productivity paradox, and sustained technological progress in ICT and expansion of ICT usage could have boosted the productivity growth. Therefore, this study implies that facilitating ICT progress and ICT usage outside of the already well-performing ICT manufacturing can help Korean economy raise the productivity growth rate.

The role of ICT in Korea’s economic growth: Productivity changes across industries since the 1990s

This paper investigates the hypothesis that technological convergence has been a major driving force for the recent productivity increase in Korea. Based on the dynamic panel data of Korean industries, the direct impact of information and communication technology (ICT) on labor productivity is assessed through growth accounting, and the indirect network effect of ICT on industrial total factor productivity (TFP) is estimated. The results confirm the essential role of broadband networks for successful convergence. The policy implications for the regulatory change are drawn from the empirical analysis.     

A multi-criteria game theory and real-options model for irreversible ICT investment decisions

The information and communication technology (ICT) industry is one of the most capital intensive among the high-technology industries. ICT business analysis, especially after the industry deregulation, has become a difficult task. Traditional quantitative cost–benefit analysis concerning investment decisions is by no means sufficient for capturing the complexity of the problem in its entirety. This work combines quantitative and qualitative analyses for modeling competitive interactions between players in the ICT business field. The proposed decision analysis model combines real options, game theory, and analytic hierarchy process for analyzing ICT business alternatives under the threat of competition. The proposed model is applied to a real broadband technology business case, showing how it can be formulated and solved.     

External knowledge search,innovative performance and productivity in the Korean ICT sector

In recent years, Korea’s Information and Communication Technology (ICT) industry has grown rapidly. The prosperity of the ICT industry has brought growing recognition that rising productivity and innovative performance have made major contributions to ensuring competitive advantage in international markets. In this context, recent studies stress the importance of external knowledge for improving both innovative performance and productivity. This paper empirically investigates the effects of firms’ external knowledge search behavior on their productivity as well as their innovative performance in the Korean ICT manufacturing sector. Based on firm-level data from the Science and Technology Policy Institute (STEPI), this study indicates that incremental innovation and productivity are both related to external knowledge search.     

Measuring convergence of China's ICT industry: An input-output analysis

The convergence of the information and communication technology (ICT) industry is ubiquitous phenomena, which can be classified from the supply/demand side or complementary/substitute relation. According to the classification, the paper measures the convergence of China's ICT sectors based on its 2002 input-output (IO) table, including five manufacturing sectors and two service sectors. Then, using IO table cross-entropy updating technique, the paper investigates the convergence evolution of four ICT manufacturing sectors from 1997 to 2002. The research finds the following conclusions. In 2002, the supply side convergence of manufacturing sectors was higher than that of service sectors, while service sectors featured a higher degree of the demand side convergence. The year of 2002 witnessed high complementary convergence between some China's ICT manufacturing and service sectors. During the period from 1997 to 2002, the supply side convergence dominated the convergence of China's ICT industry, while the demand-side convergence experienced little structural change.

Corporate Real Estate Ownership and Productivity Uncertainty

This article empirically tests the relationship between corporate real estate (CRE) holdings and productivity risks of firms. Using a large sample of public listed U.S. firms for the period from 1984 to 2011, we show that CRE ownership is significantly and negatively correlated with productivity risks of firms. Firms with high‐productivity risk own less CRE assets. When testing dynamic changes to CRE holdings, we estimate a significant and positive elasticity of CRE investments of 5.2% in response to cash flow shocks. If the adjustment cost is high, high‐risk firms are expected to hold less CRE assets, so that they could reduce potential losses associated with CRE holdings when negative productive shocks occur.     

ICT as a source of output and productivity growth in Finland

This paper analyses the impacts of information and communications technology on output and labour productivity growth in Finland in 1995–2005. Information and communications technology (ICT) accounted for 1.87 percentage points of the observed labour productivity growth at the average rate of 2.87 per cent. The contribution from increases in ICT capital intensity was 0.46 percentage points. The rest is attributed to multi-factor productivity growth in ICT production, especially in telecommunications production. The ongoing outsourcing of ICT production to low-wage countries provides a threat to productivity performance in the future. Policy makers should consider where the next wave of productivity growth will come from.     

Heterogeneous Investor Sentiment and Institutional Real Estate Investments

Commercial real estate investors differ in their sentiment due to factors such as market expertise, investment strategies and expectations about future market conditions. Focusing on the office market, we investigate whether investors with a multiasset investment focus such as pension funds or insurance companies rely on the sentiment of specialized real estate investors such as public REITs or private developers/owners as source of information in their investment decision‐making. Using disaggregated sentiment measures and vector autoregression (VAR) we find evidence that changes in REIT and private real estate investor sentiment lead to changes in institutional investor sentiment in the suburban office and office REIT market. Our findings suggest that institutional investors rely on the sentiment of specialized real estate investors to make real estate investment decisions. Our study contributes to the existing literature on sentiment in commercial real estate markets by emphasizing the heterogeneity of investor sentiment and introducing a disaggregated sentiment measure. We also contribute to the institutional herding literature.

Analysis of the Characteristics of Individual Investors in Real Estate Securities and Income-Producing Property

Analysis of the responses to a nationwide survey of investors demonstrates that individuals who invest in real estate differ in a predictable way from those who invest in assets other than real estate. Two types of real estate investment vehicles are studied: income-producing (rental) property and real estate securities. A multiple group discriminant analysis model is presented which successfully classifies prospective investors into four groups (owners of income property only, real estate securities only, both, neither) with a predictive accuracy more than double the chance probability of correct classification. The results provide insights useful in policy analysis and the design and marketing of real estate investments.     

Does ICT create a new driving force for manufacturing?—Evidence from Chinese manufacturing firms

The Internet has changed the global economic landscape. In particular, the fast-changing Information and Communication Technology (ICT) has directly led to a far-reaching impact on the production and operation of firms. Many previous studies have discussed the relationship of ICT and the total factor productivity (TFP) of firms, but failed to reach a consistent conclusion. This paper, based on the data of Chinese listed manufacturing firms from 2010 to 2019, explores the impact of ICT on manufacturing firms' TFP and its mechanism, and concludes that ICT have positive correlation with the TFP of manufacturing firms. According to the estimated results of this paper, TFP will increase by about 1.8 % for every 1 % of additional ICT investment. Through channel analysis, this paper finds that the positive effect can be achieved through the following four channels: cutting information search costs, enhancing information processing capabilities, reducing internal capital misallocation, and promoting R&D efficiency. This paper is a supplement to research on firm TFP, provides new micro-evidence for exploring the relationship between ICT and TFP of manufacturing firms, and brings important implications for understanding the role of ICT in firm production activities.
