Was the Green Revolution intended to maximise food production?

The evidence on yields, food-production, food-calories per capita, and declining levels of malnutrition in countries experiencing a Green Revolution are commonly cited in support of the claim that the GR sought to maximise food production. If one looks closely at the actual design of GR programmes (in India and elsewhere), however, it is clear that they were instead intended to boost yields and profitability in a small number of targeted areas. The underlying rationale for targeting was that achieving very high yields in such regions would persuade farmers to abandon subsistence farming in favour of commercial production, relying upon the market for the purchase of inputs as well as the sale of produce. In response to widespread criticism of the Green Revolution ca. 1970 for neglecting the needs of peasant farmers (as well as accentuating rural unrest), the World Bank and other donors began to direct more attention and resources to smallholders, but the aim of commercialising farming remained unchanged.     

How many factors are important in U.K. stock returns?

I use the sequential approach of Harvey and Liu ([2018]. Lucky factors (Working Paper). Duke University) to build linear factor models in U.K. stock returns among a set of 13 candidate factors using individual stocks and three groups of test portfolios between July 1983 and December 2017. My study finds that the Market factor is the dominant factor in reducing mispricing in individual stocks and test portfolios regardless of the pricing error metric used. The Market factor has a bigger impact when using a value weighting pricing error metric. Whether a second factor is used or not depends upon which metric is used for mispricing and the time period examined. My study finds support for a two-factor model for the whole sample period of the Market factor and the Conservative Minus Aggressive (CMA) factor of Fama and French ([2015]. “A five-factor asset pricing model.” Journal of Financial Economics 116: 1–22) when giving greater weight to the mispricing of larger companies.     

The Information Content of Guidance and Earnings

I compare the information content of quarterly earnings guidance and quarterly earnings by examining their associations with current and future stock returns when the two signals are bundled at earnings announcements. At the bundled announcement, I find a significantly stronger association between announcement returns and guidance news. From the day after the bundled announcement through the next earnings announcement, both signals generate abnormal return drifts of about 200 basis points. However, the timing of the post-announcement returns differs considerably. For guidance, about 50% of the post-announcement drift occurs at the next earnings announcement. In contrast, for earnings, about 20% of the preceding drift reverses at the next earnings announcement. Investor ignorance of the drift following guidance news coupled with a fixation on post-earnings announcement drift potentially explains this surprising difference in the timing of the post-announcement returns. Overall, this study indicates that bundled quarterly earnings guidance contains more information than quarterly earnings and that investors incorrectly overweight the earnings news and underweight the guidance news during the post-announcement period until the next earnings announcement.     

Measuring the dynamics of APEC output connectedness

We examine the dynamics of output connectedness of Asian Pacific Economic Cooperation (APEC) economies using time‐varying, region‐specific, generalised connectedness measures. We find that the connectedness of APEC economies with the rest of the world is quite substantial, with the 2008–09 Global Financial Crisis increasing the connectedness measures above their precrisis levels. The USA, China, and Korea are shown to be systemically important and to dominate APEC’s real activities, while outside the APEC region the roles of India and the UK are also non‐negligible. These results suggest that the majority of APEC economies are considerably open to output shocks from the dominant economies such that policymakers in APEC must be continuously conscious of headwinds originating from these sources.     

The cost of diabetes and obesity in Australia

Aims: To assess and compare the direct healthcare and non-healthcare costs and government subsidies by body weight and diabetes status.

Methods: The Australian Diabetes, Obesity and Lifestyle study collected health service utilization and health-related expenditure data at the 2011–2012 follow-up surveys. Costing data were available for 4,409 participants. Unit costs for 2016–2017 were used where available or were otherwise inflated to 2016–2017 dollars. Age- and sex-adjusted costs per person were estimated using generalized linear models.

Results: The annual total direct cost ranged from $1,998 per person with normal weight to $2,501 per person with obesity in participants without diabetes. For those with diabetes, total direct costs were $2,353 per person with normal weight, $3,263 per person with overweight, and $3,131 per person with obesity. Additional expenditure as government subsidies ranged from $5,649 per person with normal weight and no diabetes to $8,085 per person with overweight and diabetes. In general, direct costs and government subsidies were higher for overweight and obesity compared to normal weight, regardless of diabetes status, but were more noticeable in the diabetes sub-group. The annual total excess cost compared with normal weight people without diabetes was 26% for obesity alone and 46% for those with obesity and diabetes.

Limitations: Participants included in this study represented a healthier cohort than the Australian population. The relatively small sample of people with both obesity and diabetes prevented a more detailed analysis by obesity class.

Conclusion: Overweight and obesity are associated with increased costs, which are further increased in individuals who also have diabetes. Interventions to prevent overweight and obesity or reduce weight in people who are overweight or obese, and prevent diabetes, should reduce the financial burden.
