Commodity cycle challenges macro and financial stability
I Commodity price volatility has affected commodity-exportersmacro performance, through now well-known changes inincentives to borrow/lend in presence of financial frictions2
I This kind of risk to oil exporting economies is usuallyuninsured in international financial markets and the macro andfinancial adjustment works through the real exchange rate(RER) and net foreign financial assets (NFA)
I Furthermore, with financial frictions (collateral constraints)there is a pecuniary externality: agents do not internalize whenthey borrow in “good times” that high leverage causes collapsein collateral values and credit crunch in “bad times” (Fisheriandeflation)

There is uncertainty about commodity price fundamentals
I Under-appreciating the true process of commodity prices isnatural because of uncertainty about the duration of thehigh/low price regimes, as well as the lack of knowledge aboutthe true factors behind commodity price fundamentals.
I Natural resources are known to be affected by politicalinstability, changes in their market structure, structuralchanges in technology to exploit them, shifts in globaldemand, etc.
I As a result, discovering the true process of commodity prices isan ongoing business as the academic debate also illustrates:Hamilton (2003), Rebucci and Spatafora (2006), Hamilton(2008), Kilian (2009) and Baumeister & Kilian (2015).

Commodity price beliefs interact with financial frictionsI When there is uncertainty about commodity price
fundamentals, optimistic beliefs or good news aboutcommodity prices strengthen incentives to borrow “today” andincrease expected future borrowing capacity3 but also...
I optimistic beliefs change the incentives to exploit naturalresources (real assets) affecting reserves and extraction of thecommodity
I ... and if followed by disappointing price outcomes, theprobability of a financial crisis rises because of higher leverageand the endogenous cutback in commodity extraction.
I In this paper, discrepancies between initial expectations aboutprices and actual and posterior expected prices can be animportant source of macro and financial instability because itaffects non-trivially both households and firms.

Equilibrium under Bayesian learning about commodity prices
I Follow Boz and Mendoza (2009) two-stage solution strategy:1. Bayesian learning. Take a history of price realizations observed
up to date t, pt = (pt
, pt�1, pt�2, . . . , p1) and generate a
sequence of posterior density functions�
f
�
Q
B | pt�
T
t=1 overT periods. Each f is a probability distribution over possibleQ
B ’s. The date t = 0 priors depend on the assumed amountof agents prior knowledge.
2. The problem can be divided into a sequence of AUoptimization problems (AUOP) for t = 1, 2, . . . ,T , eachconditional on E

is an indicator variable that records whether oil pricesare high or low and ✏
t

I We apply Hamilton (1989) Markov switching estimator onquarterly real oil prices covering the period 1970:1 to 2014:2.As a proxy for real oil prices we take the BRENT crude oilprice in nominal US dollars deflated by the United StatesConsumer Price Index. The base year for the US CPI is 1983.
I Take the model ergodic moments under REPI to match bothaggregate and sectoral (oil) Colombian data.

Price collapse after a long period of high prices
I Experiment: we date the start of the high commodity priceregime in the 2009:4 and its end on 2014:3. The low oil priceregime goes from 2014:4 to 2016:1. We assume that agentshave uninformative initial priors and experience the high-oilprice regime during five years, followed by a year and a half oflow prices.
I Case 1: the sequence of revenues is {pt
x
t
}Tt=1 with
{xt
= d}Tt=1. This case is analogous to a small open economy
with a stochastic endowment of tradable goods.
I Case 2: commodity extraction is endogenous and responds tothe random movements of commodity prices and we take thesequences {p
t
}Tt=1 and {x̃
t
(p, s)}Tt=1.

Final Remarks
I We presented a framework to analyze the interaction betweenuncertainty about commodity price fundamentals and financialfrictions.
I Model of natural resource extraction, incomplete financialmarkets and endogenous borrowing constraints capture macrodynamics (calibrated to Colombia and its oil sector)
I We showed how discrepancies between initial expectationsabout prices and actual and posterior expected prices can bean important source of macro and financial instability becauseit affects non-trivially both households and firms.
I Work in progress:I Analyze the quantitative effects of alternative beliefsI Shocks to R may be additional sources of uncertaintyI Oil ownership and operations may matterI Financing extraction operations
