Foreign aid and the quality of economic institutions

Identification of the causal effect that foreign aid has on the quality of institutions in recipient countries has been elusive in the aid effectiveness literature. The main reason is that aid is endogenous with respect to the development of institutions. Our paper examines the impact of foreign aid on economic freedom in the recipient countries at a disaggregated level using an innovative identifying strategy. To do so, we use recently innovated instruments for aid, exploiting the long lags between loan approval and disbursements by official creditors to developing countries. Using plausibly exogenous variations in predicted loan disbursements as instruments for actual aid, we find that foreign aid has a significant positive effect on the quality of economic institutions in recipient countries. The results are robust to alternative specifications and samples. By establishing the existence of a strong link between aid and the quality of economic institutions, we identify the main channel through which aid affects economic growth and development.     

INFORMATION AGGREGATION,GROWTH, AND FRANCHISE EXTENSION WITH APPLICATIONS TO FEMALE ENFRANCHISEMENT AND INEQUALITY

We develop a model of voluntary gradual franchise extension and growth based on the idea that voting is an information aggregation mechanism. A larger number of voters means that more correct decisions are made, hence increasing output, but also implies that any incremental output must be shared among more individuals. These conflicting incentives lead to a dynamic model of franchise extensions that is consistent with several real world episodes, including female enfranchisement. The model also predicts that in certain circumstances growth and enfranchisement will be accompanied by Kuznets curve type behaviour in inequality. Contrary to the preceding literature these conclusions do not rest on incentives for strategic delegation.     

Comparative persistence and adherence with newer anti-hyperglycemic agents to treat patients with type 2 diabetes in the United States

Objectives: Non-adherence and non-persistence to anti-hyperglycemic agents are associated with worse clinical and economic outcomes in patients with type 2 diabetes. This study evaluated treatment persistence and adherence across newer anti-hyperglycemic agents (canagliflozin, dapagliflozin, sitagliptin, saxagliptin, linagliptin, liraglutide, or exenatide).

Methods: This retrospective cohort study of Truven Health Analytics Marketscan databases included adult patients with type 2 diabetes whose first pharmacy claim for a newer anti-hyperglycemic agent was between February 1, 2014 and July 31, 2014. Treatment persistence and adherence were assessed for 12 months after the first claim (post-index). Persistence was defined as no gap ≥90 days between the end of one pharmacy claim and the start of the next pharmacy claim post-index. Adherence used two definitions: proportion of days covered (PDC) and medication possession ratio (MPR). Multivariable analyses of non-persistence (hazard ratios) and adherence (odds ratios) were adjusted for baseline demographics, drug cost, clinical characteristics, and other anti-hyperglycemic agents.

Results: A total of 11,961 patients met all study selection criteria. Persistence rates at 12 months were significantly greater (p?p?=?0.83; PDC?=?0.79) and canagliflozin 300?mg (MPR?=?0.92; PDC?=?0.81) were greater than for the other index anti-hyperglycemic agents (MPR?=?0.33–0.75; PDC?=?0.33–0.72). Consistent results for treatment persistence and adherence were observed in multivariable analyses that were adjusted baseline characteristics.

Conclusions: Canagliflozin was associated with better treatment persistence and treatment adherence compared with other anti-hyperglycemic agents in real-world settings.     

Three decades of productivity change in French beef production: a Färe‐Primont index decomposition

The Färe‐Primont index is used to evaluate total factor productivity (TFP) change and its components for a sample of French suckler cow farms in grassland areas in 1985–2014. The results reveal an increase in TFP of 6.6 per cent over the whole observation period, with technological progress being the major source of productivity growth. Meanwhile, efficiency decreased. Farms experienced great technological progress from 1991 to 2000. From a methodological point of view, the comparison with results obtained with Malmquist indexes shows similar trends but different magnitudes, with the Malmquist index overestimating the TFP and technological changes compared to the Färe‐Primont index. In addition, the use of a sequential approach that restricts technological change to being positive or null allows for the precise calculation of technology changes, disregarding the effects of external conditions that are captured in efficiency changes. Finally, the estimation of full dimensional efficient facets (FDEFs) that guarantees the positivity of all shadow prices used to assess the mix efficiency component of TFP change is promising.     

Aid,collective action and benefits to smallholders: Evaluating the World Food Program's purchase for progress pilot

Agricultural commodity markets in developing countries often operate in a constrained environment of prohibitive transaction costs. Consequently, smallholder farmers are only partly integrated into these markets, a situation that keeps them in a lower level of development equilibrium (poverty trap). Although cooperative institutional alternatives such as Farmers’ Organizations (FOs) may reduce transaction costs and revitalize agricultural production and commercialization, they rarely have been successful in fully delivering on these promises. Against this backdrop, the World Food Programmed (WFP) has recently implemented a multi-year and multi-country pilot to increase smallholder participation in commodity markets. The projects involved investing in physical and human capacities of Farmer Organizations (FOs) to aggregate commodities and add value, as well as locally purchasing food aid from the same. The combination of interventions was expected to increase the relative price of agricultural products, particularly staple crops. In this study, using Ethiopian panel survey data, we estimated the causal income and investment effects of the Ethiopian P4P intervention among smallholders. Using an entropy balancing (EB) model and semi-parametric difference-in-difference (DID) model, we show that the P4P intervention has increased per capita consumption by smallholders. Our additional analysis confirms that this effect is heterogeneous owing to elite capture within Farmer Organizations. We also find evidence of increased food consumption scores, increased investments in child schooling, and increased asset holding among program-participating smallholders relative to comparison farmers. Policy implications are discussed.

The effect of external audits of internal control over financial reporting on financial reporting for clients of Big 4, Second-tier,and small audit firms

The external audit of internal control over financial reporting (ICFR) is a very expensive and contentious aspect of the Sarbanes–Oxley Act (SOX). Larger public firms were first required to file a management report on and have an external audit of ICFR in 2004. Smaller public firms were first required to file a management report on ICFR in 2007 but are exempt from the audit requirement. Whereas most related prior research investigates the combined effect of management and auditor reports on financial reporting, this study examines the distinct effect of auditor reports on reporting quality. For companies audited by small auditors, we find evidence that financial reporting quality improves with an auditor report on ICFR. We find no evidence that auditor ICFR reports improve reporting quality for clients of Big 4 or Second-tier audit firms. Our study adds to the debate on the applicability of SOX Section 404 to smaller firms.     

ARBITRAGE BOUNDS FOR PRICES OF WEIGHTED VARIANCE SWAPS

We develop a theory of robust pricing and hedging of a weighted variance swap given market prices for a finite number of co‐maturing put options. We assume the put option prices do not admit arbitrage and deduce no‐arbitrage bounds on the weighted variance swap along with super‐ and sub‐replicating strategies that enforce them. We find that market quotes for variance swaps are surprisingly close to the model‐free lower bounds we determine. We solve the problem by transforming it into an analogous question for a European option with a convex payoff. The lower bound becomes a problem in semi‐infinite linear programming which we solve in detail. The upper bound is explicit. We work in a model‐independent and probability‐free setup. In particular, we use and extend Föllmer's pathwise stochastic calculus. Appropriate notions of arbitrage and admissibility are introduced. This allows us to establish the usual hedging relation between the variance swap and the “log contract” and similar connections for weighted variance swaps. Our results take the form of a FTAP: we show that the absence of (weak) arbitrage is equivalent to the existence of a classical model which reproduces the observed prices via risk‐neutral expectations of discounted payoffs.
