    Effects of Improving Infrastructure Quality on Business Costs : Evidence from Firm-Level Data
    (World Bank, Washington, DC, 2008-03) Iimi, Atsushi
    Economic development is affected by infrastructure services in both volume and quality terms. However, the quality of infrastructure is relatively difficult to measure and assess. The current paper, using firm-level data collected by a business environment assessment survey in 26 countries in Europe and Central Asia, estimates the marginal impacts on firm costs of infrastructure quality. The results suggest that the reliability or continuity of services is important for business performance. Firm costs significantly increase when electricity outages occur more frequently and the average outage duration becomes longer. Similarly, increased hours of water supply suspensions also reduce firms' competitiveness. In these countries, it is found that the total benefit for the economy from eliminating the existing electricity outages ranges from 0.5 to 6 percent of gross domestic product. If all water suspensions are removed, the economy could receive a gain of about 0.5 to 2 percent of gross domestic product. By contrast, the quality of telecommunications services seems to have no significant impact.

    Price Elasticity of Nonresidential Demand for Energy in South Eastern Europe
    (World Bank, Washington, DC, 2010-01) Iimi, Atsushi
    Recent volatility in international energy prices has revealed South Eastern Europe as one of the most vulnerable regions to such external shocks. Under the current global economic downturn, in addition, the region s energy-intensive industries are faced with the challenge of the weakening demand for their outputs. This paper casts light on the relationship between the price and the demand for energy. Based on firm level data, it is shown that the price elasticity of industrial energy demand is about -0.4 on average. There are a number of data issues to interpret the results correctly. But Albania and Macedonia are systematically found to have a relatively elastic demand for energy on the order of -0.7 to -0.8. In these countries, therefore, price adjustments would be one of the effective policy options to balance demand with supply during the period of energy crisis. In other countries, the demand response would be much weaker; pricing cannot be the only solution. Other policy measures, such as facilitation of firm energy efficiency and improvements in the quality of infrastructure services, may be required.

    Effects of Improving Infrastructure Quality on Business Costs : Evidence from Firm-Level Data in Eastern Europe and Central Asia
    ( 2011) Iimi, Atsushi
    Public infrastructure is one of the important determinants of economic growth. Not only access to but also quality of infrastructure affects firm productivity as well as people's livelihood. Frequent interruptions of the infrastructure-service supply impose extra backup costs on enterprises, hinder their timely business activities, and result in large losses of sales opportunities. This paper focuses on the impacts of improving the quality of public utilities (electricity, water supply, and telecommunications), using firm-level data from 26 transition economies in Eastern Europe and Central Asia. The results suggest that firm costs would significantly increase when electricity outages occur frequently and the outage duration becomes longer. Similarly, when more time is required to restore suspended water supply, firms' competitiveness would be weakened. Not surprisingly, the impacts tend to vary depending on industry. The construction, manufacturing, and hotel and restaurant sectors are found particularly vulnerable.

    The Impacts of Metering and Climate Conditions on Residential Electricity Demand : The Case of Albania
    ( 2011-01-01) Iimi, Atsushi
    Albania is among the most vulnerable countries to external energy shocks and climatic conditions, because of its high dependency on hydropower for electricity. Given highly volatile international energy prices and expected global warming, it is becoming increasingly important to manage the demand for electricity. However, the country has long been faced with a significant problem of electricity metering. About one-third of total energy is lost for technical and nontechnical reasons. This paper estimates the residential demand function by applying a two-stage system equation method for an endogenous censored variable, because the lack of metering makes the electricity consumption partially observable for the econometrician. It is found that metering is important to curb non-essential electricity use by households. The electricity demand could also be reduced by raising the first block rate and lowering the second block rate and the threshold between the two blocks. In addition, weather conditions and home appliance ownership would affect the demand for electricity. But the latter looks more influential than the former.
