The Role of Credit in Post-Stabilization Consumption Booms
Abstract
This paper presents an empirical investigation of the role of credit in the post-stabilization consumption booms of Mexico, Chile, and Israel. Credit from the banking sector to the private sector expanded very rapidly following the stabilizations. I show that this increase in credit reduced the proportion of consumers that were liquidity constrained in the economy. This reduction in liquidity constraints could have helped to fuel the observed consumption booms. In addition, I show that the most important channels for the expansion in credit to consumers in Mexico are the rapid remonetization of the economy, the fall in the ratio of debt held by banks to GDP held by banks, and the increase in the foreign liabilities of banks. For Chile, the most important channel is the remonetization of the economy, whereas in Israel, it is the crowding in effect from the fall in the ratio of public debt held by banks to GDP. The fact that only the crowding in effect was important for Israel, is explained by the differences between its banking system and those of the other countries.

Prior to thestabilizations,thecombinationofasmall (andmostly)inefficient bankingsystemandahigh inflationenvironmentreflectedvery lowlevelsof bankcreditto theprivate sector. particularlyconsumptioncredit. Thedrasticfallinthe inflationrates afterthestabilizations combinedwithprogressivefinancialreformsworkedto increasetheresourcesavailableto thebanking sectorto financeprivateconsumption. The ratioofbankingcreditto totalprivateconsumptionwent from 29.8 percentin 1978t098.4 percentin 1982inChile. In Mexico,the ratioof consumercredit to totalprivateconsumptionwentfrom2.9 percentin 1987to 10percentin 1992.and inIsraelthe ratioof unlinkedbankcreditto totalprivateconsumptionwentfrom 15%in 1985to 30%in 1988.67 The resultshighlightthedifferencebetweenthefinancialsectorsin MexicoandChileonthe onehand. and Israelon theother. In Mexicoallthreechannelsfor theincreaseincreditto consumersare very important;thatistheremonetizationofthe economy,thefallin theratioofdebt heldby bankstoGDP, and theincreasein foreignliabilitiesheldby banks.

In additionto thegoalsoftradeliberalizationand inflationreduction,thestabilizationplan also includedmeasuresto liberalizefinancialmarketsandease restrictionson credit. Edwardsand Cox Edwards(1991)describeChile’sfinancialmarketduringmostof the60’sand70’sas a textbook caseof financialrepression. Creditmarketswere underdevelopedandhighlydistorted;thedegreeof financialintermediationwasextremelylow, real interestrateswere negative,andreserve requirements wereextremelyhighat 100%in 1973andthen42% in 1979. Mostimportantly,creditwas rationed andallocatedusingarbitraryand inefficientcriteria. Table 1showstheratioof M2 to GDP, real interestrates, andcreditto theprivatesector.

A maxi-devaluationledto a step increasein the inflationrate. Afterseveraltries withthree “packagedeals”amongthegovernment,themajorunionorganization(theHistadrut),andthe associationof privateemployeesto lowerinflationthroughwageandpricefreezes, thegovernment introducedan exchangeratebasedstabilizationprograminJulyof 1985. The mainobjectivesof the planwere to reduceinflationand improvethebalanceofpayments. The programthatwasannouncedwasverytough:itplamed to reducethebudgetdeficitby at least5%of GNP. Thiswasachievedmostlythroughsharpcutsinsubsidiesand highertaxes. The sheqelwas initiallydevaluedby 19%andthenfixedat 1.5sheqelper dollarfor a time. Wagesand priceswere alloweda one-timeadjustmentandthenfrozenat levelsthatcauseda significantreduction 11
I 1 1 , in the realwageinthe initialmonthsof theprogram. (Brunoetal..(l99l)). Theplanwasextremelysuccessfulin reducingbothinflationandthebudgetdeficit. Inflationfellfrom 500%a year to approximately16-20%per yearoverthenextcoupleof years, and thegovernmentdeficitfellfroman averageof 15%of GNP inthepreviousdecadeto beingbalanced andevena slightsurplusin 1986.

In empiricaltestsof the PIH. however,Flavin(1981)andHayashi(1982)havefoundthat certainvariables(e.g currentdisposableincome,stockpricesetc..) haveenoughpredictivepowerto rejecttherandomwalkhypothesis.9 Thisexcesssensitivityof consumptionto anticipatedchangesin incomesuggestsan alternativehypothesis.

These correlations suggest that credit might be an important determinant of consumption if it Worksto reduce the share of households that are liquidity constrained in the economy.E/ The reduction in liquidity constraints can generate the consumption booms we observe because it allows consumers who desire to consume more. but could not due to borrowing constraints, to increase their consumption and to reduce their excess savings; or by allowing them to purchase the durables they have been waiting to buy. IV.3 Sources of Credit Expansions After Stabilizations The evidence presented in the previous section, shows that increases in credit after stabilizations play an important role in reducing credit constraints after these plans were enacted. In this section, I look at the exogenous sources of these credit expansions. There are three possible channels through which credit can increase after a stabilization. These channels are evident when looking at the following accounting identity ..,...-, ----:--<:from a bank balance sheet. private SectorLoans=Depositi- Resemes- Govt.hans (8) First, an increase in deposits given the level of public debt held by banks (and the level of reserves) increases the supply of loans to the private sector. The increase in deposits can come from the repatriation of capital held abroad as inflation stabilizes at lower levels and is reflected in the rapid remonetization of the economy as measured by an increase in M2/GDP. The second channel through which credit availability can increase after a stabilization is through a decline in the level of public debt held by banks at any given level of the ratio of ~/ If we assume that credit is exogenous.wecan write ~=~-~red, andpluggingthis intoequation(6) weget AC,=p+~AY,yAYt*cred,+ert+&,.This was estimated for all the three countries. and in each case y was negative and highly signilimt. The estimates were Y~C,K,,-=1.04,ych,l~-=1.4E-05.andY,.,~,l=-9.3E-05, indicatingthatanincreaseincredit reducesliquidityconstraints. 24
M2 to GDP. Resources from the financial sector which were previously being used to finance the government can now be used to finance the private sector. This crowding in effect of a lower level of public debt occurs independently of the increase in the volume of financial intermediation. Each of these channels in and of themselves, can explain the increase in availability of credit to consumption following a stabilization. This implies that any (or both) of these reasons could be the key to explaining the decline in liquidity constraints that occurs after stabilizations. In effect, the level of credit in the economy is negatively related to the level of public debt held by the banking sector (scaled by GDP), and positively related to the degree of remonetization, measured by M2/GDP. With these effects in mind, we specify the share of the population that is liquidity constrained endogenously. (9) where M2/GDP is the ratio of M2 to GDP and B/GDP is the ratio of the real stock of internal public debt held by banks to GDP.u/ We expect yto be negative and ~ to be positive. Equation (9) says that as the economy gets remonetized credit increases so liquidity constraints decrease, and that as the level of debt increases the amount of credit decreases so 1 increases. Substituting equation (9) into (6) we get (lo) ~/ Bisthesum oftheIFS1ines52an,52b,and 52cforMexico,thesumof 22a-c,42a-c,and42apfor Chile,anditisline 22a forIsrael.

‘1 where M2Y[=M2/GDP * AY~and BY,= B/GDP * AYI. I estimated equation (14) for Mexico Chile. and Israel. ~/ The results are shown in Table 11. For Mexico and Chile, it is clear that the remonetization of the economy after the stabilization was a key element in the credit expansion (and therefore in the reduction in liquidity constraints) that ensued. As expected, we see that the estimate of Yis negative and significant at the 10YOlevel. On the other hand, this is not the case for Israel. ‘I’his is not Surprising, since as we mentioned before, the financial system of Israel is very different from that of either Mexico or Chile. Its highly indexed system acts to protect depositors from inflation and devaluation risk; therefore the level of banking resources available to the private sector did not change much from before the stabilization to after it. The steadying of the exchange rate and consequent sharp drop in devaluation expectations, the drop in inflation, and the rise in real interest rates on local currency accounts led to a drastic change in financial asset holdings, notably a shift from PATAM and other resident deposits to short-term sheqel deposits. In -:~.. ..-..:- ... -~-: a Israel, people kept the money at home but they kept it in accounts linked to the dollar, when the stabilization lowered inflation, people switched from dollars to domestic currency but the amount of resources in the banking system did not change much. This is reaffirmed by the evolution of the volume of financial intermediation as measured by M3/GNP shown in Table 7. ~/ The methodof estimatim isalwaysTSM withthesame setof instrumentsasbefore. 26

Looking at the results for the estimate of ~ we see that it is positive (as expected) in all cases, but it is only significant in Mexico and Israel. This implies that for Mexico the channels through which credit expansions occurred were both a remonetization of the economy and the fall in public debt held by the banking sector. The crowding in effects from a fall in public debt held by the banking system are ulso quite important in Israel. This is logical since one of the principal objectives of the stabilization plan was to drastically reduce the deficit to GDP ratio. Even though this was the case in Chile as well, the data for Chile are very bad and some of the missing years were interpolated from the existing series. ~/ In addition to the two channels through which credit expansions can take place already mentioned, there is a third factor.

The results show that only for Mexico does the increase in foreign liabilities by the banking sector make a difference in the increase in credit and consumption. It also makes the remonetization not as important (y is significant at the 2070level). For Chile and Israel this 28
channel does not seem to matter and as before the relevant channels are the remonetization and the fall in the public debt held by banks respectively. V. CONCLUSIONS In looking at the role of credit in the post-stabilization consumption booms of Mexico, Chile, and Israel, we find that the expansions in banking credit after the stabilizations are indeed an important determinant of consumption. The paper shows that there is strong evidence against the PIH and that liquidity constraints were quite important in these countries prior to the stabilization. In addition, we see that the share of households that are liquidity constrained falls sharply after the stabilizations. This effect is strongest in the case of Mexico. The decline in liquidity constraints can generate a decline in excess savings and/or a lumping of expenditures on consumer durables which can help explain the consumption booms that we observe. In looking at the sources of credit to consumers in these economies, I find that for the case of Mexico, all three of the sources examined played an important role. Credit to consumers expanded through the remonetization of the economy, through the decrease in the ratio of debt held by banks to GDP, and through the increase in foreign borrowing by banks. For Chile, I find that only the remonetization matters; and for Israel only the crowding in effect matters. These results highlight the difference in the financial markets of Mexico and Chile on the one hand, and Israel on the other. Israel’shighly indexed and developed financial system mean that there was not a significant increase in the volume of financial intermediation after the stabilization since it was already fairly high. Consumers in Israel had access to domestic indexed credit prior to the stabilization whereas in Mexico and Chile this was not the case. This means that the impact of the increase in credit in Mexico and Chile is 29
much larger than in Israel. These results suggest that the role of the financial system in the economy is quite important when monitoring the progress ofan economy after a stabilization. A country considering an exchange rate based stabilization should be very vigilant of developments in the financial sector. More importantly, to avoid a boom-and-bust cycle and the possibility of banking crises, countries should keep their financial systems tightly monitored and regulated, particularly during the expansionary phase. . . 30

abstract = {This paper presents an empirical investigation of the role of credit in the post-stabilization consumption booms of Mexico, Chile, and Israel. Credit from the banking sector to the private sector expanded very rapidly following the stabilizations. I show that this increase in credit reduced the proportion of consumers that were liquidity constrained in the economy. This reduction in liquidity constraints could have helped to fuel the observed consumption booms. In addition, I show that the most important channels for the expansion in credit to consumers in Mexico are the rapid remonetization of the economy, the fall in the ratio of debt held by banks to GDP held by banks, and the increase in the foreign liabilities of banks. For Chile, the most important channel is the remonetization of the economy, whereas in Israel, it is the crowding in effect from the fall in the ratio of public debt held by banks to GDP. The fact that only the crowding in effect was important for Israel, is explained by the differences between its banking system and those of the other countries.},
