An agent-based model for the assessment of LTV caps

We assess the effects of regulatory caps in the loan-to-value (LTV) ratio for housing mortgages using an agent-based model. Sellers, buyers and banks interact within a computational framework that enables the application of LTV caps to a one-step housing market. We first conduct a simulation exercise; later, we calibrate the probability distributions based on actual European data from the Household Finance and Consumption Survey. In both cases, the application of an LTV cap results in a modified distribution of buyers in terms of property values, bidding prices and properties sold, depending on the probability distributions of the LTV ratio, wealth and debt-to-income ratios considered. The results are of similar magnitude to other studies in the literature embodying other analytical approaches, and they suggest that our methodology can potentially be used to gauge the impact of common macroprudential measures.     

Consumption and Hedging in Oil‐Importing Developing Countries

We study the consumption and hedging strategy of an oil‐importing developing country that faces multiple crude oil shocks. In our model, developing countries have two particular characteristics: their economies are mainly driven by natural resources and their technologies are less efficient in energy usage. The natural resource exports can be correlated with the crude oil shocks. The country can hedge against the crude oil uncertainty by taking long/short positions in existing crude oil futures contracts. We find that both inefficiencies in energy usage and shocks to the crude oil price lower the productivity of capital. This generates a negative income effect and a positive substitution effect, because today’s consumption is relatively cheaper than tomorrow’s consumption. Optimal consumption of the country depends on the magnitudes of these effects and on its risk‐aversion degree. Shocks to other crude oil factors, such as the convenience yield, are also studied. We find that the persistence of the shocks magnifies the income and substitution effects on consumption, thus also affecting the hedging strategy of the country. The demand for futures contracts is decomposed in a myopic demand, a pure hedging term and productive hedging demands. These hedging demands arise to hedge against changes in the productivity of capital due to changes in crude oil spot prices. We calibrate the model for Chile and study to what extent the country’s copper exports can be used to hedge the crude oil risk.     

High and low prices and the range in the European stock markets: A long-memory approach

This paper uses fractional integration techniques to examine the stochastic behaviour of high and low stock prices in Europe and then to test for the possible existence of long-run linkages between them by looking at the range, i.e., the difference between the two logged series. Specifically, monthly, weekly and daily data on the following five European stock market indices are analysed: DAX30 (Germany), FTSE100 (UK), CAC40 (France), FTSE MIB40 (Italy) and IBEX35 (Spain). In all cases, the order of integration of the range is lower than that of the original series, which implies the existence of a long-run equilibrium relationship between high and low prices. Further, multiple breaks are found in the high and low-price series but no breaks in the range, and the estimated fractional differencing parameter is positive in all cases, which represents evidence of long memory.     

Modelling the nonlinear relationship between oil prices,stock markets,and exchange rates in oil-exporting and oil-importing countries

This article investigates the multivariate dependence between oil prices, equity markets, and exchange rates in certain oil-importing and oil-exporting countries by applying the vine copulas approach which offers a greater flexibility and permits the modelling of complex dependency patterns for high-dimensional distributions. Our results show that the dependence between oil and exchange rates is significantly negative during different periods of analysis, except for the British Pound and Japanese Yen exchange rates. This result indicates that oil may serve as a weak hedge against exchanges rates.     

Price Setting in the Euro Area: Some Stylized Facts from Individual Producer Price Data

This paper summarizes the microevidence on the setting of producer prices in the euro area. The main findings are: (i) 21% of producer prices are adjusted each month, (ii) producer prices are changed more frequently and by smaller amounts than consumer prices (even after controlling for product characteristics), (iii) price decreases are relatively frequent, (iv) inflation correlates positively with the difference between the frequency of price increases and decreases, and (v) there is substantial variation in price flexibility across sectors, which can be explained in part by differences in the cost structure, the degree of competition, and the level of sectoral inflation.     

The Anticipated Capitalisation Effect of a New Metro Line on Housing Prices*

Housing units with closer access to public transportation enjoy a higher market value than those with similar characteristics but poorer access. This difference can be explained by the lower cost of transport to the main workplaces and shopping areas in town. For this reason, investments in public transport infrastructure, such as building a new metro line, are capitalised totally or partially into land and housing prices. This work empirically analyses the degree of capitalisation into housing prices of the benefits of the new Line 4 of the Santiago metro system, which began operating in December 2005. We focus on anticipated capitalisation into housing prices at the moment construction of Line 4 was announced and at the moment information on the basic engineering project was unveiled, identifying the location of the future stations. We use a unique database containing all home buying and selling transactions in the Greater Santiago area between December 2000 and March 2004. The results show that the average apartment price rose by between 4.2 per cent and 7.9 per cent after construction was announced and by between 3.1 per cent and 5.5 per cent after the location of the stations was identified. These increases were not distributed evenly, but depended on the distance from the apartment to the nearest station. An indirect effect of this kind of capitalization is that property tax collections will increase if property is reappraised following the price rise. This effect is not negligible in magnitude and could represent 11 to 17 per cent of investment in the new metro line. This raises and interesting discussion on how the metro network extension is financed.     

Does Bancassurance Reduce the Price of Financial Service Products?

I assess the impact of bancassurance on the price of retail financial services. I find that service fees in a product bundle increase less than proportionally to the number of services; that an increase in the number of clients in each product bundle market reduces fees by 1.5%; that the degree of competition in the markets of each bundle also reduces fees; that premium products have higher average costs; and finally, that cross-holdings reduce prices by about 5% and bancassurance reduces prices by just over 6%. The price reduction declines if both strategies are combined.

Asset Price Spillover,Collateral and Crises: with an Application to Property Market Policy

This paper studies the impact of land supply elasticity and land use regulation. For sufficiently adverse shocks constrained entrepreneurs liquidate their assets for debt repayment. This effect can spillover to the residential property market. A crisis occurs when households are forced to default on their mortgages as well. While both converting costs and land use regulation tend to magnify the effect of adverse shock, the former generates an asymmetric effect between a positive and a negative shock on the land market, and the latter tends to raise the likelihood of a crisis, by raising the threshold value of liquidation.

Long run forward rates and long yields of bonds and options in heterogeneous equilibria

We prove that, in a heterogeneous economy with scale-invariant utilities, the yield of a long term bond is determined by the agent with maximal expected marginal utility. We also prove that the same result holds for the long term forward rates. Furthermore, we apply Cramér’s large deviations theorem to calculate the yield of a long term European call option. It turns out that there is a threshold risk aversion such that the option yield is independent of the risk aversion when the latter is above the threshold. Surprisingly, the long term option yield is always greater than or equal to the corresponding equity return. That is, in the long run, it is more profitable to buy a long maturity call option on equity than the equity itself.      

Financial innovation and European housing and mortgage markets

In this paper we assess the recent history of house prices andof mortgage lending across Europe. We develop a simple economicframework to estimate the likely contributions of fundamentalfactors, such as changes in real incomes and population growth,to house price appreciation. We also try to quantify how muchof price rises might have been driven by rising expectationsof future capital gains. We estimate that this might have playeda significant role in several countries, including Spain, Sweden,Belgium, and the UK. We then consider what different types ofmortgage arrangement might become attractive in a world of higherhouse prices, analysing types of indexed mortgage that haveadvantages where prices are higher relative to incomes and wherehouse prices may be volatile and cannot be assumed to carryon rising.
