Past studies on the relationship between electricity consumption and temperature have primarily focused on individual countries. Many regions are understudied as a result of data constraint. This paper studies the relationship on a global scale, overcoming the data constraint by using grid-level night light and temperature data. Mostly generated by electricity and recorded by satellites, night light has a strong linear relationship with electricity consumption and is correlated with both its extensive and intensive margins. Using night light as a proxy for electricity consumption at the grid level, we find: (1) there is a U-shaped relationship between electricity consumption and temperature; (2) the critical point of temperature for minimum electricity consumption is around 14.6°C for the world and it is higher in urban and more industrial areas; and (3) the impact of temperature on electricity consumption is persistent. Sub-Saharan African countries, while facing a large electricity deficit already, are particularly vulnerable to climate change: a 1°C increase in temperature is estimated to increase their electricity demand by 6.7% on average.

This Selected Issues paper explores the economic consequences of aging and its impact on long-term fiscal sustainability for Cyprus. The study analyzes the potential macroeconomic impact of different approaches to deal with the fiscal costs of aging. It goes beyond a simple quantification of the fiscal impact by explicitly examining the trade-offs of alternative policies within the context of a general equilibrium overlapping generation framework. It is concluded that addressing the fiscal consequences of aging will require increasing the retirement age to 65 years, followed by further increases to keep up with demographic trends.

This Selected Issues paper and Statistical Appendix provides a brief assessment of Cyprus’s external position and its composition in an international perspective. It discusses estimates of Cyprus’s external position based on partial International Investment Position data as well as on cumulative flows, and compares its level and composition with advanced Organization for Economic Cooperation and Development (OECD) economies and with other accession countries. It finds that a precise assessment of Cyprus’s overall external position is hindered by the lack of data on nondebt stocks. The paper also analyzes aging and long-term fiscal sustainability in Cyprus.
