Complex Samples and Regression‐Based Inference: Considerations for Consumer Researchers

This article demonstrates that researchers who treat data collected via complex sampling procedures as if they were collected via simple random sample (SRS) may draw improper inferences when estimating regression models. Using complex sample data from the 2004 panel of the Survey of Income and Program Participation (SIPP) two models—one ordinary least squares (OLS) regression and one logistic regression—were estimated using three methods: SRS with and without population weights, Taylor series linearization, and Fay's Balanced Repeated Replication (BRR). The results of the alternative models demonstrate that depending on the variables of interest, authors who fail to incorporate sample design information or fail to consider the effects of weighting may draw improper inferences from their regression models. Reasons why researchers continue to neglect complex sample‐based variance are proposed and discussed, and example SAS and Stata code is offered to encourage adoption by the consumer research community.     

Endowment,industrial structure,and appropriate financial structure: a new structural economics perspective

Standard policy advice at times of fiscal adjustment is to protect public spending on the poor. However, the political economy of fiscal adjustment could well indicate the opposite direction, to protect the non‐poor from adjustment. This point is illustrated by three case studies based on research on social programs in Argentina, Bangladesh, and India, focusing on how targeting performance varied with aggregate outlays. The results suggest a tendency for program spending on the non‐poor that is protected from budget cuts.     

Trade Impacts of China's World Trade Organization Accession

This study examines China's World Trade Organization (WTO) accession commitments and assesses their implications for China and the world using a model reflecting the importance of duty-free intermediate inputs in China's exports. The WTO agreement built on earlier reforms that introduced competition into the trade regime, eliminated nontariff barriers and exchange rate overvaluation, and reduced tariffs. The reforms associated with accession were conservatively estimated to increase global real incomes by $74 billion per year, with $29 billion accruing to China and the remainder primarily to those countries trading directly with China. Some lower-income developing countries faced greater competition from China in third markets.     

The Economics of Television Regulation: A Survey with Application to Australia*

The analysis of the regulation of television poses a number of challenges to economists Because the structure and organization of television broadcasting are rarely the same between any two countries, there are difficulties in applying the economic analysis of television regulation in one country to that of another. Further, the major social and cultural role of television causes government broadcasting policy to include many non-economic objectives This paper outlines the main issues concerning the economic regulation of television and relates the prominent literature in the area to the Australian broadcasting environment     

WESTERN FARM LABOR ISSUES

This paper examines three farm labor issues: (1) how mechanization affects the demand for farm labor; (2) how immigration reform affects the supply of farm workers; and (3) how 10 years of collective bargaining affect the farm labor market. The evidence suggests that mechanization, immigration reform, and collective bargaining have had or will have fewer effects on the farm labor market than is often assumed. However, the farm labor market is vulnerable to future shocks if it remains isolated from nonfarm labor markets.     

Balance Sheet Effects, Bailout Guarantees and Financial Crises

This paper provides a model of boom-bust episodes in middle-income countries. It is based on sectoral differences in corporate finance: the nontradables sector is special in that it faces a contract enforceability problem and enjoys bailout guarantees. As a result, currency mismatch and borrowing constraints arise endogenously in that sector. This sectoral asymmetry allows the model to replicate the main features of observed boom–bust episodes. In particular, episodes begin with a lending boom and a real appreciation, peak in a self-fulfilling crisis during which a real depreciation coincides with widespread bankruptcies, and end in a recession and credit crunch. The nontradables sector accounts for most of the volatility in output and credit.
