Abstract
My doctoral research contributes to the fields of macroeconomics and international
finance. Within macroeconomics, I have explored the role of financial frictions
in shaping macroeconomic outcomes following a recession. I have studied the dissonance
between the rapid improvement in financial conditions and the sluggish
recovery in investment observed in the aftermath of the Great Recession. In related
research I also analyze the fast improvement in financial conditions and analyze the
existence of a positive feedback between asset prices and leverage through the lens
of liquidity shocks. Within international finance, I have an empirical and theoretical
interest in the analysis of capital flows. My research in this area has focused
on the role of domestic investors in preventing economies from experiencing the
largely-documented pervasive effects of net sudden stops in capital flows, and its
determinants.
Chapter 1. The rapid improvement in financial conditions and the sluggish recovery
of physical investment in the aftermath of the Great Recession are difficult to
reconcile with the predictions of existing models that link impaired access to credit and investment. I propose a tractable model that solves this puzzle by exploiting
the role of customer markets in shaping the persistent effects of financial shocks
on investment decisions. In my model, firms react to a negative financial shock by
reducing expenditures in sales-related activities and increasing prices to restore internal
liquidity, at the expense of customer accumulation. Once financial conditions
start reverting to normal levels, the firm postpones investment due to a shortage
of customers relative to its existing production capacity and the need to first rebuild
its customer base. This mechanism can capture two important features of the
data: First, the slow recovery of investment despite improving financial conditions,
and second, the positive correlation between financial conditions and investment
observed during downturns and the weakening of this correlation observed during
upturns.
Chapter 2. I assess how the inclusion of complementary sources of liquidity can
have sizeable reinforcing effects during a crisis and in its aftermath. In this paper,
I allow for the possibility to finance investment projects either by selling existing
capital units or by borrowing using the units not sold as collateral. The main
characteristic of this model is that capital is heterogeneous and composed by units of
different quality, which are only observed by the owner. The asymmetric information
on capital quality makes both, the asset prices at which investors can sell their
assets and the loan-to-value (i.e. leverage) ratio at which they can borrow to be
endogenously determined. The simultaneity in the determination of asset prices and
leverage lead to the existence of liquidity spirals. For instance, a negative exogenous
shock that reduces leverage creates a fall in the funds available to finance capital purchases (i.e. a decline in demand). It also increases the supply for assets in the
market, since entrepreneurs require selling more units to finance the same amount
of investment. These two effects create unambiguously a fall in prices. The fall
in prices reinforces the initial fall in loan-to-values since lenders expect the quality
of units used as collateral to be lower. This mechanism explains why alternative
sources of liquidity fall rapidly during downturns, and why liquidity can recover
faster during upturns.
Chapter 3. This paper, which is joint work with Eduardo Cavallo and Alejandro
Izquierdo, explores the determinants behind the decision of domestic investor to
adjust their asset position in response to a variation in gross capital inflows and avoid
episodes of net sudden stops. We present evidence that while sudden stops in gross
inflows are associated with global conditions, domestic factors such as the degree
of domestic liability dollarization, economic growth and institutional background
are important to prevent these episodes in becoming net sudden stops. We also
extend the concept of “Prevented Sudden Stops” and differentiate “Delayed” from
“Purely Prevented” episodes. A purely prevented episode is one in which there is
not a sudden stop in any of the quarters for which there was a sudden stop in gross
inflows. A delayed episode is one in which there is at least one quarter in which
there was both a sudden stop in gross inflows and a net sudden stop. We want
to analyze how this classification can affect the extent to which economic growth
and domestic liability dollarization can still account for the offsetting behavior of
domestic investors.
