Decades of agricultural development policy have chased yield. Bigger harvests, better seeds, more fertiliser. But how can we make farming more profitable? Craig McIntosh of UC San Diego is academic lead on a J-PAL Policy Insight covering twenty-three randomised evaluations of credit and grants for farmers in low- and middle-income countries. He tell Tim Phillips that although yields and revenues often rise, profit rarely responds in the same way. When farmers are already running their farms close to the margin, costs rise at the same rate as income, and the household bank balance does not move much. What can we bundle with credit to change that situation?The research behind this episode:Abdul Latif Jameel Poverty Action Lab (J-PAL). 2026.

His research spans development finance, agricultural credit, cash transfer design and the evaluation of large-scale anti-poverty interventions. Research cited in this episodeMicrocredit take-up among farmers. Across four randomised evaluations of traditional microcredit aimed at farmers, in Morocco, Ethiopia, Bangladesh and Malawi, take-up sat between 13 and 33 percent. Standard microcredit repayment begins a week or two after disbursement, which is incompatible with a crop cycle that pays out cash once or twice a year. Group liability also breaks down in agriculture, where shocks like drought or floods hit borrowers together rather than one at a time.Tailoring credit to the agricultural cycle. Restructured loans push take-up much higher. Nakano and Magezi in Tanzania allowed rice farmers to defer 80 percent of repayment until harvest; 39 percent borrowed and over 92 percent repaid. William Jack and co-authors in Kenya offered dairy farmers asset-collateralised loans for a water tank; take-up reached 44 percent against 2.4 percent for a typical joint-liability product. Lambon-Quayefio, Manjeer and Udry in Ghana offered digital credit with a three-month grace period; 59 percent of farmers took it up.Sell low, buy high. Burke and co-authors in Kenya showed that smallholders routinely sell at the post-harvest price trough and buy back grain at hungry-season prices 20 to 40 percent higher. Harvest-time loans that allowed farmers to delay sales had take-up of 64 percent and produced returns around 29 percent for borrowers. Treated villages also saw flatter price trajectories, generating spillover benefits for non-borrowers.Lean-season credit. Fink, Jack and Masiye in Zambia found that lean-season loans let farmers stop hiring out their labour and instead work their own land. Output rose by 9 percent. Loan repayments were comparable to the gain, leaving farmers roughly even on profits.Selection into credit markets. Beaman, Karlan, Thuysbaert and Udry in Mali first offered loans, then offered grants to those who had refused. Returns to capital among would-be borrowers were on the order of 130 percent. Returns among those who had refused the loan were close to zero. Credit appears to self-target toward farmers who can use it productively, which is regressive in welfare terms and also exactly what a capital-scarce economy needs credit markets to do.Input subsidy programmes (ISPs). Jayne and co-authors reviewed eighty studies of fertiliser subsidies across sub-Saharan Africa. Yields rise while subsidies are in place; profitability is mixed; targeting is frequently politically distorted, often skewed toward better-connected or wealthier farmers. The standout randomised exception is Carter, Laajaj and Yang in Mozambique, where two-thirds of recipients had never used fertiliser before; the programme produced sustained gains and a high benefit-cost ratio. By contrast, Gignoux and co-authors in Haiti found a fertiliser-voucher subsidy crowded out farmers' own input spending and lowered yields once the subsidy ended.Cash transfers and diversification. In six studies measuring both farm and non-farm outcomes, three found households doubled down on agriculture and three saw movement into non-farm enterprises. The Zambian Child Grant evaluation by Handa and co-authors saw women invest in seeds, fertiliser and livestock and start non-farm businesses, with household income roughly doubling.Bundled input programmes. Four randomised evaluations bundled credit or a grant with information, training or market access. All four lifted revenues; three of the four lifted incomes or profits. Harou and co-authors in Tanzania showed that fertiliser vouchers alone and soil testing alone did nothing; only the combination raised yields and revenues. Ashraf, Gine and Karlan's Kenya study on French-bean and baby-corn export found credit increased programme participation from 27 to 41 percent, even where it did not further raise income among participants.

In 2017, Argentina had the highest corporate income tax rate in Latin America. Reducing it was politically popular and economically desirable. Getting it through a Congress where the governing coalition held just 19% of Senate seats, while the fiscal deficit ran at close to 8% of GDP, was a harder problem. A package of reforms was planned, revenue-neutral and phased over five years: corporate tax on reinvested profits would fall from 35% to 25%; a minimum-wage deduction would reduce the payroll tax burden on firms employing informal workers; energy, alcohol, and sugar taxes would be reorganised on rational, emissions-based principles; and provincial governments would agree to phase out the cascading "ingresos brutos" sales tax in exchange for limits on public spending. In this week’s VoxDev Talk, Sebastian Galiani, who served as Deputy Minister of Economy in Argentina and led the design of the reform, tells Tim Phillips how the Macri government attempted to reform its tax structure, and what it teaches us about policy. Credibility, he says, was the biggest constraint: in a country as economically volatile as Argentina, what matters is not only what the law says, but whether investors believe it will survive a change of government.The research behind this episode:Afonso, Santiago, and Sebastian Galiani. 2025.

His research spanning political economy, public finance, and Latin American development has examined how institutions, property rights, and fiscal policy shape economic outcomes. He served as Deputy Minister of Economy in Argentina in 2017, where he led the design of the tax reform he examines in this episode.Research cited in this episodeIngresos brutos is a cascading sales tax levied by Argentina's provincial governments, applied each time a good changes hands along the supply chain. Unlike a value-added tax, it allows no deduction for taxes already paid at earlier stages; the burden compounds with the length of the production chain, making it particularly punishing for manufactured goods that pass through many hands. Galiani's team negotiated a deal under which the provinces agreed to phase this system out over five years and move toward a simpler, less distortive sales tax structure.Second-best reform is the practice of improving a policy system as far as constraints allow rather than designing for the theoretically optimal outcome that cannot be achieved in practice. Galiani frames the 2017 reform explicitly in these terms: the design team mapped the distance between Argentina's actual tax system and optimal taxation, then asked how far they could move in that direction given the fiscal, political, and negotiating constraints they faced. The result departed from the ideal in every dimension; it was nonetheless a genuine improvement on what existed before.Escape clauses are provisions written into legislation that suspend or modify specific commitments if defined trigger conditions are met. The 2017 reform included several: the inflation adjustment for the calculation of corporate assets, for example, would apply only if inflation continued to fall. Galiani describes escape clauses as essential when designing policy in high-volatility environments where external shocks are not exceptional events but a predictable feature of the landscape.Related reading on VoxDevHow should economic researchers give policy advice? Stefan Dercon argues that giving second-best advice, taking into account what is politically achievable rather than what is theoretically optimal, often produces better outcomes than the standard model of advocating for the ideal and waiting.How progressive taxation affects tax compliance in developing countries. Reforms that boost progressivity and are effectively communicated can yield higher compliance alongside greater fairness; evidence that the design and communication of a reform matter as much as its content.Improving payroll-tax compliance through decentralised monitoring: Evidence from Mexico. Evidence that even formal firms evade payroll taxes, and that giving workers the right incentives to monitor their employers' wage reporting can substantially improve compliance; relevant context for Argentina's effort to reduce the payroll tax burden on unskilled workers.

At the start of every planting season, smallholder farmers needs seeds and fertiliser, but the income from the harvest that would pay for them is many months away. With no credit history and no collateral, banks aren’t going to give credit to farmers.They cope by selling livestock, pledging part of the harvest to a trader at a discount, or turning to neighbours.Can we do a better job of lending to farmers? Monica Lambon-Quayefio of the University of Ghana tells Tim Phillips about a digital lending product for farmers in southern Ghana shows what this approach can do — but also where it still falls short. Working with Farmerline, a social enterprise that scores creditworthiness from farm and sales data rather than formal records, the trial randomly assigned eligible applicants to receive input loans worth around $40. Farm input expenditures rose by around 11%. But not profits.

Rich people live longer than poor people in every country that researchers have studied. In the United States today, the gap in life expectancy between the richest and poorest 1% of individuals exceeds ten years. The relationship between money and health is steepest at the bottom of the income distribution, where additional resources buy the most: when people are poor, there is a great deal that money can do for their health. In this week’s episode, Adriana Lleras-Muney of UCLA tells Tim Phillips that the evidence on the relationship between poverty and health is less certain than policymakers tend to assume. Causality runs in both directions: poor health is one of the fastest routes into poverty, and understanding how much of the association flows in each direction is still an active debate. Giving poor people more money does not reliably translate into better health within the timescales and amounts that most experiments can test, because the details matter: how long the transfer lasts, whether it is conditional, and what receiving it signals about a person's economic future all shape what they actually do with it.The most consistent finding from the policy evidence is that public health insurance and access to cheap, proven preventive interventions tend to deliver more reliable health gains than cash transfers — but whether either works in practice depends heavily on the implementation and the trust that governments can build with the populations they are trying to help.The research behind this episode:Lleras-Muney, Adriana, Hannes Schwandt, and Laura R.

Eighty years after Indian independence, the economic fingerprint of British colonial rule is still visible at the district level. Two institutions in particular left scars: whether a district was governed directly by British administrators or by one of India's roughly 680 Indian princes, and what kind of land tax arrangement the British put in place. For example, by 1991, directly ruled districts had nine percentage points fewer middle schools and a 20-percentage-point lower probability of having a road than areas under indirect rule. The question was whether those gaps would eventually close.Lakshmi Iyer of the University of Notre Dame tells Tim Phillips that by 2011 infrastructure gaps had closed completely. Targeted post-independence programmes, including the Minimum Needs Program of the 1970s and the Sarva Shiksha Abhiyan of 2001, pushed schools, health centres, and roads towards underserved districts. The picture for land tenure is mixed. Areas that historically had landlord-based systems are still 17% behind non-landlord areas in wheat yields, and the gap in fertiliser use has widened rather than narrowed. One reason, the policy response was a universal subsidy rather than being specifically aimed at places that had fallen behind.So colonial legacies can be erased, but only by policies designed to reach the places that were left behind. When policies have equalisation built in, historical gaps disappear. When they do not, the gaps persist.The research behind this episode:Iyer, Lakshmi and Coleson Weir. 2025.

China became the world's largest bilateral creditor to developing countries over two decades, and for most of that time the scale of what it was doing was effectively a state secret. Its state-owned banks lent close to $1 trillion to developing-country governments, structured roughly half those loans against commodity export revenues held in offshore accounts, and concentrated the riskiest lending in countries such as Venezuela, Angola, and Russia. Net financial flows turned negative in 2019, and the countries that borrowed now repay more to China than they receive in new lending.Sebastian Horn of the Kiel Institute tells Tim Phillips that despite the opacity and the distinctive collateral structures, we’ve seen this movie before, in the 1920s and 1980s: in the bust, serial short-term extensions of grace periods that defer payments without resolving the underlying debt, while affected countries cut spending to stay current. What Horn calls a "silent crisis" is underway in a cluster of highly indebted developing countries, too small to trigger global contagion but large enough to matter profoundly for the people living through it.The challenge is whether China's lenders, debtor governments, and the broader international financial architecture can coordinate the kind of relief that will make a difference.The research behind this episode:Horn, Sebastian, Carmen M.

Between 2019 and 2023, the number of electronic transactions tripled in six Latin American economies. The share of adults using digital wallets, mobile money, and mobile bank accounts went from 3% in 2011 to 40% by 2021. A region that not long ago was defined by financial disasters, hyperinflation, and deep mistrust of banks has become one of the world's leading examples of how digital payments can transform an economy.Diego Vera-Cossio edited Beyond Cash, The Digital Payments Revolution in Latin America and the Caribbean, the Inter-American Development Bank's new regional microeconomic report on digital payments. He tells Tim Phillips how the effects of this revolution are more profound that freeing people from the need to carry cash. In Santiago, bus robberies fell when drivers stopped handling cash. In Brazil, firms in the most cash-intensive sectors grew substantially after the instant payment system Pix launched. In Colombia, people without any credit history started borrowing formally after being nudged to receive their social program payments digitally. And in Bolivia, where 80% of the workforce is informal, people are scanning QR codes at street market stalls. The question Diego, his colleagues, and policymakers int he region and beyond, are now trying to answer is how to build on all of that, and how to make it stick.The research behind this episode:Vera-Cossio, Diego A., ed. 2025.
