Micro-Climate Engineering for Climate Change Adaptation in Agriculture

Job Market Paper

Can farmers adapt to climate change by altering effective weather conditions on their fields? Technologies for small scale temperature adjustment are used by farmers, yet receive little attention in the economic literature. These technologies allow farmers to cool down plants by a few degrees on hot days, reducing the damage from excess heat. With non-linear effects of high temperature on yields, slight cooling can bring significant gains in many crops. I call this approach “Micro-Climate Engineering” (MCE), and note that it could be useful as a climate change adaptation concept. Climate change is predicted to harm crops mainly by change of the temperature distribution tails, rather than by change of the averages. I develop a model to analyze grower choice and market outcomes with MCE under adverse climate, and apply it to assess the potential gains from an existing MCE technology in California pistachios, which are threatened by warming winters. The expected yearly gains from MCE technologies by the year 2030 are assessed at 153 - 540 million US dollars under several scenarios. Simulation results show a total negative gain from MCE for the pistachio growing sector, but the positive gains for consumers surpass them. Adding market power in the growing sector increases consumer gains from MCE, but grower incentives to apply MCE technologies (and invest in new ones) become sensitive to market conditions.

Agricultural GMOs - What We Know and Where Scientists Disagree

Published review paper

Population growth, climate change, and increasing human impact on land and aquatic systems all pose significant challenges for current agricultural practices. Genetic engineering is a tool to speed up breeding for new varieties, which can help farmers and agricultural systems adapt to rapidly changing physical growing conditions, technology, and global markets. We review the current scientific literature and present the potential of genetically modified organisms (GMOs) from the perspectives of various stakeholders. GMOs increase yields, lower costs, and reduce the land and environmental footprint of agriculture. The benefits of this technology are shared among innovators, farmers, and consumers. Developing countries and poor farmers gain substantially from GMOs. Agricultural biotechnology is diverse, with many applications having different potential impacts. Its regulation needs to balance benefits and risks for each application. Excessive precaution prevents significant benefits. Increasing access to the technology and avoidance of excessive regulation will allow it to reach its potential.

Disability Insurance Reform and Labor Supply: Evidence from Israel

(With Yotam Shem-Tov)

In 2009, Israel reformed its Disability Insurance program, replacing a strict earning cap for beneficiaries with a gradual offset of benefits. This kind of program has been discussed in the US for over 20 years today. Using administrative data from Israel, the goal of this project is to estimate the effect of this reform on labor supply of beneficiaries, and on DI enrollment. Preliminary findings show strong labor supply effects on those beneficiaries who were employed prior to the reform; insignificant effect on those who didn’t; and no effect on the characteristics of newly enrolled beneficiaries.

Past

I have a masters degree in environmental studies. In my thesis, I focused on solid waste policies in Israel. Solid waste (“garbage”) is a major environmental issue, and I hope to keep doing research on it.

Should we blame the rich for clogging our landfills?

(With Alon Tal)

Abstract: Conventional wisdom often holds that relatively high consumption levels among the affluent contributes to the generation of high volumes of municipal solid waste (MSW). Comparing data from different cities in Israel suggests otherwise. Regression analysis reveals that aggregate per-capita waste outputs of cities are only vaguely correlated with their socio-economic indicators. In fact, the apparent ‘hedonic’ waste of the richest cities, compared with the average ones, accounts for only about 2% of the total waste production. Israel’s main economic area, the Tel Aviv district, produces a quarter more MSW per capita than other districts, suggesting a need for special attention by policy makers. A surprisingly strong predictor of MSW per capita is water consumption by municipalities, dedicated for public gardening. The trimmings of the municipal landscape constituting an unobserved fraction of total MSW data, are estimated to be responsible for 15% of Israel’s MSW, making it an additional target area for consideration and intervention.

What Drives Municipal Solid Waste Policy Making? An Empirical Assessment of the Effectiveness of Tipping Fees and Other Factors in Israel

(With Alon Tal)

Abstract: What factors influence the waste policy of local authorities? While central governments make efforts to promote recycling, the major players in municipal waste management are local authorities. This paper explores the factors influencing waste policies of local authorities in Israel in light of the new landfill tax legislated in 2007. Based on interviews with officials overseeing waste management and other stakeholders, a model of waste policy making in local authorities is proposed. A survey among waste officials of local authorities then evaluates the influence of general and specific factors on associated municipal policies. Cost of landfilling and a new landfill tax, is reported as highly influential on waste policies. Other factors, such as the Mayor’s motivation, managerial capacity in the municipality, and recycling markets are also highly influential. While the cost of landfilling is easily targeted by the central government, the latter factors are seldom addressed.
