Time to Vote?

Despite the centrality of voting costs to the paradox of voting, little effort has been made to accurately measure these costs outside of a few spatially limited case studies. In this paper, we apply Geographic Information Systems (GIS) tools to validated national election survey data from New Zealand. We calculate distance and travel time by road from the place of residence to the nearest polling place and combine our time estimate with imputed wages for all sample members. Using this new measure of the opportunity cost of voting to predict turnout at the individual level, we find that small increases in the opportunity costs of time can have large effects in reducing voter turnout.paradox of voting, opportunity cost, travel time

Which households are most distant from health centers in rural China? Evidence from a GIS network analysis

In this paper we have two objectives - one empirical; one methodological. Although China’s leaders are beginning to pay attention to health care in rural China, there are still concerns about access to health services. To examine this issue, we use measures of travel distances to health services to examine the nature of coverage in Shaanxi Province, our case study. The mean distance by road to the nearest health center is still more than 6 kilometers. When we use thresholds for access of 5 and 10 kilometers we find that more than 40 (15) percent of the rural population lives outside of these 5 (10) kilometer service areas for health centers. The nature of the access differs by geographical region and demographic composition of the household. The methodological contribution of our paper originates from a key feature of our analysis in which we use Geographic Information System (GIS) network analysis methods to measure traveling distance along the road network. We compare these measures to straight-line distance measures. Road distances (produced by network analysis) produce measures (using means) that are nearly twice as great as straight-line distances. Moreover, the errors in the measures (that is, the difference between road distances and straight-line distances) are not random. Therefore, traditional econometric methods of ameliorating the effects of measurement errors, such as instrument variables regression, will not produce consistent results when used with straight-line distances

Efficient remittance services for development in the Pacific

Capital inflows to the Pacific islands from aid, foreign investment and remittances are an important source of development finance. Remittances are the fastest growing; they now total US$400 million per year and can be expected to grow even further as labour mobility is used to deal with seasonal labour shortages in Australia and New Zealand and limited job opportunities in the Pacific. The transaction costs of sending remittances to the Pacific islands are very high for the most widely used methods. This paper examines the New Zealand- Tonga remittance corridor, where typical transactions involve costs in the order of 15 to 20 per cent for bank drafts and transfers through money transfer companies such as Western Union. Cheaper transfer methods using automated teller machines (ATMs) are feasible and have transaction costs of less than 5 per cent but are not widely used. This spread of 10 percentage points between the most popular and the cheapest remittance methods means a potential loss for Tonga of the equivalent of 4 per cent of GDP. Extrapolating from this remittance corridor to the rest of the Pacific, avoidable transaction costs may total US$ 40 million per year. Hypotheses about the continued reliance on high transaction cost methods are examined and implications for development policy are discussed

What determines preferences for an electoral system? Evidence from a binding referendum

Much has been written about politicians' preferences for electoral systems, yet little is known about the preferences of voters. In 1993, New Zealand had a binding electoral referendum on the same day as the general election where voters chose between keeping a single plurality system (First Past the Post) or introducing a pure proportional one (Mixed Member Proportional). This paper merges data from all nationwide polling stations to Census data on local voters to examine what drives citizens' preferences for an electoral system. We find that strategic partisan interest was a key driver: voters overwhelmingly preferred the system that most benefited their favorite party. However, socioeconomic characteristics and social values also mattered; people who held more progressive values, were outside the dominant religion and lived in urban areas were much more likely to vote to change to a proportional system. Survey data show that these findings hold at the individual level, and further, that individuals who were angry with the economy were much more likely to vote against the status quo, regardless of their background, party preferences or social values. This behavior is likely to have ultimately balanced the result in favor of Mixed Member Proportional

Testing an Information Intervention: Experimental Evidence on the Effect of Jamie Oliver on Fizzy Drinks Demand

We conducted a salient purchasing experiment to test if an information intervention alters fizzy drinks demand. Subjects in our experiment initially made five rounds of purchases, for 14 items (energy drinks, colas, and lemonades) selected from a stratified sample of retailers. Subjects faced seven pricing environments, reflecting baseline prices, two ad valorem taxes, two specific taxes, and ad valorem and specific price cuts to reflect retailer discounting. Subjects then watched a video presentation by celebrity chef Jamie Oliver, which highlighted adverse health effects of sugary drinks. The five rounds of choices were then repeated, to generate within-subject before and after demands that show an overall 25% reduction in purchases due to the information intervention. Demand for one sugar-free option, Diet Coke, rose 36% after the intervention. The impacts under baseline prices were little different to those seen in conjunction with tax-induced price rises. Effects of the information intervention were larger for females, for the young, for the less educated, for those usually spending more on soft drinks, and for those who usually ignore sugar content when making purchases

Which Night Lights Data Should we Use in Economics, and Where?

Popular DMSP night lights data are flawed by blurring, top-coding, and lack of calibration. Yet newer and better VIIRS data are rarely used in economics. We compare these two data sources for predicting Indonesian GDP at the second sub-national level. DMSP data are a bad proxy for GDP outside of cities. The city lights-GDP relationship is twice as noisy using DMSP as using VIIRS. Spatial inequality is considerably understated with DMSP data. A Pareto adjustment to correct for top-coding in DMSP data has a modest effect but still understates spatial inequality and misses key features of economic activity in Jakarta

Economic Growth and Expansion of China’s Urban Land Area: Evidence from Administrative Data and Night Lights, 1993–2012

The relationship between economic growth, expansion of urban land area and the broader issue of cultivated land conversion in China has been closely examined for the late 1980s and 1990s. Much less is known about recent urban expansion and if the effects of economic growth on this expansion have changed over time. This paper updates estimates of urban expansion for China and examines the relationship with city economic growth for 1993–2012. To see if patterns are robust to different types of evidence, administrative data on the area of 225 urban cores are compared to estimates of brightly lit areas from remotely sensed night lights. The trend annual expansion rate in lit area is 8% and was significantly faster in the decade to 2002 than in the most recent decade. Expansion is slower according to administrative data, at just 5% per annum, with no change in unconditional expansion rates between decades, while conditional expansion rates have declined. The elasticity of area with respect to city economic output is about 0.3. Over time, expansion of urban land area is becoming less responsive to the growth of the local non-agricultural population
