Broadband adoption and content consumption

We explore how broadband access drives changes in the quantity and diversity of consumption of online content by using panel data that describes household Internet usage before and after broadband adoption. Our data suggests that on average, broadband adoption increases usage by over 1300 min per month. We also find that information consumption becomes more evenly distributed within the population, driven in part by post-adoption usage gains of almost 1800 min per month among individuals who were in the lowest usage quintile before adopting broadband. After adopting broadband, this pre-adoption lowest-usage quintile consumes content in greater quantities than users in neighboring quintiles, passing both the second and third quintiles in terms of absolute usage. This suggests that these users may have had strong preferences for high-bandwidth content that was too costly to consume in a narrowband environment. We also show that broadband adoption increases the variety of content that users consume although many of these gains appear to be associated with an increase in the variety of sites visited within previously visited content categories rather than an expansion in the types of content consumed.     

Modelling the demand for optional classes of local measured telephone service

There is currently a strong movement under way in the telephone industry to unbundle access charges and usage charges for local telephone service. Pricing schemes with separate access and usage charges are called measured service options. Predicting which option a household will choose involves analysing a selection problem, referred to as the choice of class of service. This choice is estimated in a nested logit framework. The three major findings of this study are that the measured options are perceived as being very similar, many personal calls may originate from businesses if the pricing structure is changed, and that the flat rate price will have to be nearly doubled before the ‘take rate’ for flat rate pricing is significantly diminished.     

Takeovers, Joint Ventures and the Acquisition of Resources for Diversification

This paper explores the influence of acquisition costs on the choice between the takeover and joint venture modes of obtaining the resources required for diversifying expansion. It uses the conditions created by privatisation in the UK utility sector as a natural experiment to examine the determinants of mode choice across groups of firms with unusually homogeneous opportunity sets. The empirical design is able to incorporate acquirer, target and geographical market variables as explanatory factors in mode choice. It is shown that the form of diversifying expansion adopted is highly sensitive to the anticipated costs of using the acquisition process.     

Discrete Choice Analysis of Demand for Broadband in Japan

The remarkable development of Japan’s broadband (BB) market has attracted attention worldwide. This paper is one of the first to analyze Japan’s BB demand (including FTTH) using a discrete choice model. Our main conclusions are first, there is a distinction between narrowband (NB) and BB services based on a nested choice structure. Second, considering own-price elasticities of access demand, ADSL is inelastic, but FTTH and CATV are elastic. Third, in ADSL submarkets, low-speed and high-speed ADSL are becoming more elastic.     

Dimensions of international expansions by US firms to China: Wealth effects,mode selection,and firm-specific factors

China's recent efforts to attract foreign investment have been viewed favorably by US firms, who have explored a variety of strategies for expanding to China. This paper provides evidence related to a comprehensive set of strategies used by US firms to expand to China. For the 302 announcements of expansion by US firms into the Chinese market, several firm-specific factors are found to affect both the choice of mode entry and the reaction of investors to the announcement of the expansion. The results suggest that firms with a high investment in proprietary assets prefer foreign direct investment (FDI) modes to non-FDI modes, as do firms with high levels of geographic diversification. Firms entering the Chinese market utilize non-FDI modes, while those who have established a presence in China prefer FDI modes. The reaction of the stock market to expansions to China is positive; average excess returns of 0.75% are observed for the two days surrounding the announcement. Both FDI and non-FDI categories of expansion have statistically significant excess returns. Analysis by mode of expansion shows that expansions through joint ventures (JVs) and contracts are the most desirable alternatives. Other modes of expansion do not result in significant excess returns. Finally, a firm's prior financial performance has a significant influence on its ability to profitably expand to China.     

Timing and determinants of local residential broadband adoption: evidence from Ireland

This article examines the time path of broadband adoption for households in areas that are offered broadband service for the first time and the socioeconomic characteristics of broadband users generally. Using cross-sectional data on broadband take-up and socioeconomic characteristics of small areas in Ireland, linked to GIS data on ADSL availability over time, I find that local penetration growth rates are elevated immediately after service is offered. Local growth rates then decline towards the national average, reaching it after about 3.6 years. The article also includes estimates of the effect of various household characteristics on adoption, finding effects broadly consistent with the previous literature. Simultaneity in demand and supply are addressed using 2SLS regression.     

AN EMPIRICAL ANALYSIS OF CHILD CARE DEMAND IN SWITZERLAND

ABSTRACT ** :  This paper analyzes the demand of Swiss families for child care facilities. A choice experiment is used to study the effects of the facilities' characteristics as well as socio-economic factors on the selected child care mode. The experimental data are analyzed using a discrete choice model with multinomial logit specification. The results suggest that the demand for extra-familial day care could be considerably higher than that observed from the actual choices constrained by insufficient provision of affordable day care. The price, access, and the quality of service as well as parents' income and education have important impacts on the choice of the mode of care.     

The role of WiBro: Filling the gaps in mobile broadband technologies

This paper analyzes WiBro, one of the emerging wireless technologies for portable Internet services (PIS), which are designed to enable mobile broadband access. Based on an empirical examination of consumer preferences for mobile broadband technologies and an estimation of the future demand for WiBro, this study proposes that WiBro should fill the gaps between competing mobile broadband technologies, such as 3G and WLAN.     

Distortions,infrastructure, and female labor supply in developing countries

In this paper I document cross-country gaps between gross domestic product (GDP) per capita and GDP per worker. The gaps are driven mostly by a lower female labor force participation (LFP) in developing countries. Females began to participate more in the labor markets of these countries when more households acquired access to basic infrastructure and when distortive policies affecting the prices of household appliances were partially removed. I use a model of home production with endogenous labor force participation to account for these facts. I find that the prices of household appliances and access to infrastructure are quantitatively important in explaining cross-country labor supply differences.     

Demand estimation and market definition for broadband Internet services

This paper analyses residential demand for Internet access in Austria with a focus on broadband Internet connections. Austria has cable network coverage of about 50% and is, therefore, a good candidate to analyse the elasticity of demand for DSL where cable is available and where it is not. We also include mobile broadband via UMTS or HSDPA in our analysis and estimate various nested logit models to derive conclusions for market definition. The estimation results suggest that demand for DSL is elastic and that cable networks are likely to be in the same market as DSL connections both at the retail and at the wholesale level. We discuss possible implications for the regulation of wholesale broadband access markets.

The choice of foreign market entry mode: An analysis of the dynamic probit model

Based on the official survey data of Taiwanese FDI in China, this study investigates the transaction cost determinants of foreign market entry mode choice. In contrast to the existing literature, this paper constructs a panel data set and makes a dynamic probit analysis on the mode choice between wholly-owned subsidiaries and joint ventures. Empirical results indicate that state dependence between current and past modes plays an important role in determining entry mode choice. However, the impact of state dependence will be reduced significantly if the mode adopted in the previous period is associated with poor performance of the parent firm. There is strong linkage between mode performance and future mode choice. Evidence also shows that the hypothesized influences of transaction cost factors on entry mode choice gain support in the dynamic choice process.     

Precautionary Saving and Health Insurance: A Portfolio Choice Perspective

This paper analyzes the impact of health insurance on household portfolio choice. Using the U.S. Survey of Consumer Finance and Health Retirement Survey databases, it finds that insured households are more likely to own stocks and invest a larger proportion of financial assets in stocks than uninsured households do. The results remain strong even after controlling for household characteristics and reverse causality. Further, the results are robust across different survey years and data sources. It suggests that a precautionary motive is strong in household portfolio choice decisions.     

On selecting a technology evolution path for broadband access networks

The rapid growth in the number of Internet users has accelerated the use of high-speed Internet access services, including broadband multimedia services. In the delivery of broadband multimedia services to end-users, it is necessary to build a high-speed backbone and access network. To construct a broadband access network, several alternative technologies including xDSL, CATV, and FTTx have been suggested and implemented in telecommunication networks. However, even if a technology is proven to be optimal for the current environment, it can be deteriorated by the elapse of time or the advent of new challenging technologies in the future. In this article, we concentrate on the selection of an evolution path for broadband access networks. We developed an optimization model for selecting the best technology and evolution path with the minimum total cost. The problem can be formulated as a mixed integer programming model. With a scenario for demands and cost factors, we find the optimal evolution path by solving our model with the CPLEX program and illustrate some sample paths for the broadband access network evolution plan. Once the cost and the demand are defined in detail to reflect the real-world case, our model can be useful to generate a practical technology evolution plan for broadband access networks in real-world applications.     

Buying a Home with a Resale Value: Location,Location, Location*

We develop a dynamic multiregion model, where a household's choice of housing location depends on its current wealth and its current type, and involves both consumption and investment considerations. The relative strength of the consumption motive and the investment motive determines the equilibrium pattern of residential sorting. A strong investment (consumption) motive implies sorting according to household type (wealth). The model predicts that large house‐price fluctuations are associated with a low degree of sorting by type. This prediction is consistent with evidence from US metropolitan areas when income, education, and age are used as proxies for household type.     

Rural development in the digital age: Does information and communication technology adoption contribute to credit access and income growth in rural China?

Information and communication technology (ICT) plays an important role in rural livelihoods and household well-being. Therefore, this study examines the impact of ICT adoption on farmers' decisions to access credit and the joint effects of ICT adoption and access to credit on household income using 2016 China Labour-force Dynamics Survey data. Both recursive bivariate probit model and a selectivity-corrected ordinary least square regression model are employed for the analysis. The results show that ICT adoption increases the probability of access to credit by 12.8% in rural China and empowers rural women and farm households in relatively less-developed regions to access credit. ICT adoption and access to credit affect household income differently. ICT adoption significantly increases household income, while access to credit significantly reduces it, primarily because farmers do not use the acquired credit to invest in income-generating farm and off-farm business activities. ICT adoption has the largest positive impact on household income at the highest 90th quantile. Our findings suggest that improving rural ICT infrastructure to enhance farmers' ICT adoption and developing ICT-based financial products to enable households to access sufficient funds can improve rural household welfare.

Business Demand for Broadband Access Capacity

Using data garnered from a quarterly survey of U.S. business establishments from 2Q2000 through 1Q2001, the study estimates an aggregate model of business demand for broadband access capacity. The primary goal is to estimate price elasticities for the demand for access capacity conditional on a business establishment having made the decision to adopt some form of broadband access. The primary findings are (1) on average, the demand for broadband access capacity is price inelastic; (2) the sensitivity to price differs substantially across establishments of different sizes with small establishments exhibiting the greatest sensitivity to price; and (3) the estimated elasticities have important implications for public policies designed to extend broadband networks to unserved areas.     

Historical legacies in savings: Evidence from Romania

This study explores channels of savings persistence using a spatial regression discontinuity across an imperial border in present-day Romania. With data obtained from a lab in the field experiment and household survey, the findings suggest that imperial history influences savings behaviors today. I find no evidence that economic preferences for risk and time differ across the border, nor that these preferences are culturally transmitted. Rather, imperial history is strongly correlated with current financial access and asset choice, which affect savings accumulation. To confirm the robustness of these findings, I conduct falsification tests that arbitrarily move the border and also rule out several alternative mechanisms, including trust in financial institutions, financial literacy, and migration. I establish the external validity of the field experiment using nationally-representative data, which also suggests that savings legacies have important welfare consequences for the ability to mitigate household shocks. These findings highlight the role of history in under-saving, as well as the reinforcing nature of culture and institutions in shaping contemporary economic outcomes.     

Regulated price reforms and unregulated substitutes: the case of residential piped gas in Argentina

This paper examines the impact of regulated piped gas price changes on connection decisions and households’ welfare. The analysis explicitly considers bottled gas as a substitute for piped gas and therefore uses a simple utility maximization model that yields both a gas-type choice model and a demand specification whose parameterization allows examining households’ responses to regulated price changes. The results show that relative gas prices and household features explain households’ piped gas usage. They also provide insights on the distribution of welfare changes. The findings illustrate the impact of tariff rebalancing and unregulated substitutes on further access to regulated network services.
