This paper investigates to what extent the seminal contribution of Samuelson (1954) hasbeen or not incorporated by the theories of general equilibrium and mechanism designin their analysis of optimal public good provision and more generally of optimal publicpolicy. Our conclusion is that, far from taking up the challenges raised by Samuelson’scontribution, both paradigms lead to...

We show that municipalities’ credit constraints can have important effects on local economies through a ratings channel. We identify these effects by exploiting exogenous variation on U.S. municipal bond ratings due to Moody’s recalibration of its ratings scale in 2010. We find that local governments increase expenditures and employment due to an expansion of their debt capacity following a rat...

Banks are growing ever larger compared to their national economies. We show that increases in relative bank size (measured as a bank’s liabilities divided by national GDP) are linked to banks displaying higher tail risk. This effect is not entirely due to risk channels that disproportionately expose relatively large banks to systematic tail risks, sovereign risks, or banking crises. Instead, we...

We formulate and study the requirement on an allocation rule that no agent should be able to benefit by augmenting his endowment through borrowing resources from the outside world (alternatively, by simply exaggerating it). We show that the Walrasian rule is not “borrowing-proof” even on standard domains. More seriously, no efficient selection from the endowments-lower-bound correspondence, or ...

The evolution of economies during the major portion of human history was marked by Malthusian Stagnation. The transition from an epoch of stagnation to a state of sustained economic growth has shaped the contemporary world economy and has led to the Great Divergence in income per capita across the globe in the past two centuries. This entry examines the process of development over the course of...

Three dimensions of the performance of firms in Ghana’s manufacturing sector are investigated in this paper: their technology and the importance of technical and allocative efficiency. We show that the diversity of factor choices in not due to a non-homothetic technology. Observable skills are not quantitatively important as determinants of productivity. Technical inefficiency is not lower in f...

Gravity Equations are broadly used to estimate the impacts of trade impediments on trade flows. It is often stated that results are implausibly high. In theoretical foundations of the gravity equation, trade costs usually enter as "icebergmelting-costs". This paper offers an alternative approach to model trade costs. From a microeconomic point of view, trade costs should depend on trade input p...

A popular methodology of studying spatial income inequality is analysis of beta-convergence (i.e. an inverse relationship between current income per capita and its initial level). Its widespread use is based on a belief that the economic growth theory predicts income convergence among economies (countries or regions within a country), and that beta-convergence suggests decreasing income inequal...

This paper uses a panel of state-level data to test whether changes in bank loan supply affect output. Since the U.S. states are small open economies with fixed exchange rates, state-specific shocks to money demand are automatically accommodated, leading to changes in lending if banks rely on deposits as a source of funding. Using these shocks as an instrumental variable, I find that shocks to ...

What leads the United Nations Security Council (UNSC) to intervene in one conflict, but remain inactive in another? This paper analyzes all 221 documented conflicts between 1945 and 2011, trying to unveil the characteristics associated with UN intervention. Including geographical aspects, we find that proximity to two the five permanent members of the UNSC has a significant and meaningful effec...
