Inflation targeting in Brazil: constructing credibility under exchange rate volatility

This paper assesses the challenges faced by the inflation-targeting regime in Brazil. The inflation-targeting framework has played a critical role in macroeconomic stabilization. We stress two important challenges: construction of credibility and exchange rate volatility. The estimations indicate the following results: (i) the inflation targets have worked as an important coordinator of expectations; (ii) the Central Bank has reacted strongly to inflation expectations; (iii) there has been a reduction in the degree of inflation persistence; and (iv) the exchange rate pass-through for “administered or monitored” prices is two times higher than for “market” prices.     

Money and inflation in the euro area: A case for monetary indicators?

This paper examines inflation indicators for the euro area by studying the relationship between inflation, output, money and interest rates, using data spanning 1980–2001. The central finding is that both the output gap and the real money gap (the difference between the real money stock and the long-run equilibrium real money stock) contain considerable information regarding future inflation. In contrast, the Eurosystem's money-growth indicator (the difference between nominal money growth and a reference value), the prominent “first pillar” in its monetary strategy, contains little information about future inflation, and no information beyond that contained in the output and real money gaps. The predictive performance of the output gap has improved compared to that in a previous version of this paper, most likely because of better estimation methods.     

Learning and the monetary policy strategy of the European Central Bank

This paper examines the welfare implications of alternative inflation targeting proposals for the monetary policy of the European Central Bank. We assume that policy makers have to “learn” the laws of motion of inflation in an economy characterized by “stickiness” in domestic price setting behavior and subjected to recurring shocks to productivity, exports and foreign price. We find that a switch from an “asymmetric” inflation targeting strategy to an “symmetric” makes little difference in welfare payoffs, but it comes at a cost of much higher interest-rate variability. We also find that there are practically no welfare gains from switching from an inflation-targeting strategy based on the Harmonized Index of Consumer Prices (HICP) to a strategy based on the domestic price component of the HICP.     

Inflation accounting in a theory of calculation

How should we conceptualize the issue of inflation accounting? This is the problem raised and discussed in this paper. It represents a case study of the recent U.K. inflation accounting debate, but tries to set this within the context of how financial calculation more generally is organised and its social determinants. Two particularly distinctive features of the analysis are the ways in which this debate is related to the idea of financial calculation as “sign”, and the non-reduction of the “interests” located in the debate to expressions of some pre-given social position. Finally the wider implications of this non-orthodox approach are assessed.     

Information Uncertainty and Expected Returns

This study examines the role of information uncertainty (IU) in predicting cross-sectional stock returns. We define IU in terms of “value ambiguity,” or the precision with which firm value can be estimated by knowledgeable investors at reasonable cost. Using several different proxies for IU, we show that (1) on average, high-IU firms earn lower future returns (the “mean” effect), and (2) price and earnings momentum effects are much stronger among high-IU firms (the “interaction” effect). These findings are consistent with analytical models in which high IU exacerbates investor overconfidence and limits rational arbitrage.This revised version was published online in August 2005 with a corrected cover date.     

The behavior of money and other economic variables: Two natural experiments

The object of this paper is to test the performance of the quantity-theory model and the related proposition of monetary neutrality in a context in which, to use Bernanke's phraseology, “money move[d] for reasons that [were] plausibly unrelated to the current state of the economy.” We investigate this question using data from two recent episodes of monetary-policy regime change – the move to floating exchange rates throughout the industrialized world following the breakdown of Bretton Woods in the early 1970s and the shift toward less expansive monetary policy that to varying degrees took place in these countries a decade or so later. The results of this exercise are highly positive. The money–price relationship that we observe is fully consistent with theory – growth shifts in the nominal stock of money and in the price level are highly correlated and bear a one-to-one relation to one another. Growth shifts in exchange rates are significantly related both to growth shifts in relative price levels and to growth shifts in relative excess supplies of money. The classical neutrality proposition – in this context superneutrality – in general, receives strong, though not totally unambiguous, support.     

Mediating instruments and making markets: Capital budgeting, science and the economy

We examine in this paper how certain instruments link science and the economy through acting on capital budgeting decisions, and in doing so how they contribute to the process of making markets. We use the term “mediating instruments” to refer to those practices that frame the capital spending decisions of individual firms and agencies, and that help to align them with investments made by other firms and agencies in the same or related industries. Our substantive focus is on the microprocessor industry, and the roles of “Moore’s Law” and “technology roadmaps”. We examine the ways in which these instruments envision a future, and how they link a multitude of actors and domains in such a way that the making of future markets for microprocessors and related devices can continue. The paper begins with a discussion of existing literatures on capital budgeting, science studies, and recent economic sociology, together with the reasoning behind the notion of “mediating instruments”. We then address the substantive issues in three stages. Firstly, we consider the role of “Moore’s Law” in shaping the fundamental expectations of an entire set of industries about rates of increase in the power and complexity of semiconductor devices, and the timing of those increases. Secondly, we examine the roles of “technology roadmaps” in translating the simplified imperatives of Moore’s Law into a framework that can guide and encourage the myriad of highly uncertain and confidential investment decisions of firms and other agencies. Thirdly, we explore one particular and recent example of major capital investment, that of post-optical lithography. The paper seeks to help remedy the empirical deficit in studies of capital budgeting practices, and to demonstrate that investment is much more than a matter of valuation techniques. We argue, through the case of the microprocessor industry, for greater attention to investment as an inter-firm and inter-agency process, thus lessening the fixation in studies of capital budgeting on the traditional hierarchical and bounded organization. In addition, we seek to extend and illustrate empirically the richness of the notion of “mediating instruments” for researchers in accounting, science studies, and economic sociology.     

tay's as good as cay: Reply

In a recent comment on our published work [Lettau, M., Ludvigson, S., 2001. Consumption, aggregate wealth, and expected stock returns. Journal of Finance 56, 815–850], Michael Brennan and Yihong Xia [2005. tay's as good as cay. Finance Research Letters 2, 1–14] advance the following argument: A “mechanistic” variable tay, where t is a linear time trend, forecasts stock returns. Since “t has no foresight,” the argument goes, the predictive power of this variable must be attributable to what they call “look-ahead bias.” The authors assert that cay is subject to the same look-ahead bias (generated because we use the full sample to estimate the cointegrating parameters in cay), implying that its forecasting power must be spurious. In this response, we explain why this critique is misplaced.     

Overreaction in the Hong Kong stock market

Overreaction reported in the equity markets of the United States, Spain, and Brazil is also observed in the Hong Kong stock market. The “loser” portfolios of the 33 stocks in the Hang Seng Index (HSI), on average, outperform the “winner” portfolios by 9.9% 1 year after the formation periods. Besides its emphasis on the importance of the Hong Kong market in international investment, this paper is unique in some special features related to the overreaction study. Hong Kong has markets for index futures and stock futures. Only three stocks are used in the portfolios. All the stocks in the HSI have large market capitalization and liquidity and can be shorted with no up-tick rule. Unlike other studies in international stock markets, the “arbitrage” portfolio of buying the loser portfolio and shorting the winner portfolio can actually be formed with minimum cost and easy execution, which makes the overreaction phenomena in this study very powerful.     

Further evidence on the rationality of interest rate expectations

This paper extends the limited work on interest rate expectations to a previously unexploited data set that covers a broad range of EMS and non-EMS foreign currency deposits. We corroborate the earlier finding in the literature that interest rate forecasts are not rational and that agents do not use all available information in an efficient manner; this finding applies to the post-1990 period, thus questioning the assertion of Frankel and Froot [Frankel, J.F., Froot, K.A., 1987a. Using survey data to test standard propositions regarding exchange rate expectations. American Economic Review 77, 151] that “the nature of the rejection of rational expectations strongly depends on the sample period”. Although forecast errors on EMS rates are smaller and less volatile than errors on non-EMS rates, expectations on EMS rates are nevertheless biased.     

A Bayesian analysis of a variance decomposition for stock returns

We apply Bayesian methods to study a common vector autoregression (VAR)-based approach for decomposing the variance of excess stock returns into components reflecting news about future excess stock returns, future real interest rates, and future dividends. We develop a new prior elicitation strategy, which involves expressing beliefs about the components of the variance decomposition. Previous Bayesian work elicited priors from the difficult-to-interpret parameters of the VAR. With a commonly used data set, we find that the posterior standard deviations for the variance decomposition based on these previously used priors, including “non-informative” limiting cases, are much larger than classical standard errors based on asymptotic approximations. Therefore, the non-informative researcher remains relatively uninformed about the variance decomposition after observing the data. We show the large posterior standard deviations arise because the “non-informative” prior is implicitly very informative in a highly undesirable way. However, reasonably informative priors using our elicitation method allow for much more precise inference about components of the variance decomposition.     

Financialized accounts: Share buy-backs, mark to market and holding the financial line in the S&P 500

In recent years the US corporate sector has deployed more cash from operations to finance the repurchase of outstanding share capital for treasury stock. Shares repurchased for treasury stock can help flatter earnings per share, fund senior management share option compensation schemes and finance corporate acquisitions. In financialized accounts these are now significant transactions which, it is argued, serve the financial interests of managers and investors.The US Financial Accounting Standards Board (FASB) is now demanding a “greater use of fair value measurements in financial statements” with the result that share options and corporate acquisitions will be “marked to market”. This will force a financialized ratchet because managers in the S&P 500 will need step up cash extraction if they are to hold the financial line.     

COMMON STOCK RETURNS,EXPECTED INFLATION,AND THE RATIONAL EXPECTATIONS HYPOTHESIS

This paper provides empirical evidence that expected inflation has a cross-sectional impact on common stock returns. The study differs from others in that (a) the relation between stock returns and expected inflation is investigated in a two-factor asset pricing model, where the factors are the return on an equally weighted stock portfolio and the expected rate of inflation; (b) the estimation of the expected rate of inflation is based on the rational expectations hypothesis of Muth; and (c) a non-linear seemingly unrelated regression technique is employed to determine consistent and asymptotically efficient estimates. The joint hypothesis of the two-factor asset pricing model and rational expectations is not rejected in this study. It is found that the return on common stocks is significantly affected by expected inflation. Also stocks whose returns are positively correlated with expected inflation have lower expected returns.     

Financial instruments with sports betting components: Marketing gimmick or a domain for behavioral finance?

We examine theoretically and experimentally a certain class of new financial instruments which are designed as lotteries on the outcome of prominent sports events like the Soccer World Cup 2006. From a theoretical point of view, sports betting products may be superior to a fixed rate investment because of heterogeneous expectations, risk-loving behavior of investors or additional non-monetary utility components. In comparison to the direct placement of bets at bookmakers’, sports betting products may be preferable in cases of hedonic framing. Our experimental section, however, reveals the limited practical relevance of these theoretical arguments for “average” decision makers. Despite this, financial instruments with sports betting components offer a certain profit potential due to the diversity of preferences across individuals. Summarizing, the issuance of sports betting products may actually be mainly driven by marketing aspects, nevertheless sports betting products may be considered to be “viable” niche products with low cost of capital for banks.     

Inside–outside money competition

We study how competition from privately supplied currency substitutes affects monetary equilibria. Whenever currency is inefficiently provided, inside money competition plays a disciplinary role by providing an upper bound on equilibrium inflation rates. Furthermore, if “inside monies” can be produced at a sufficiently low cost, outside money is driven out of circulation. Whenever a ‘benevolent’ government can commit to its fiscal policy, sequential monetary policy is efficient and inside money competition plays no role.

Towards a rational strategy for the human settlement of space

This paper revisits the core issues of space policy from the viewpoint of optimal decision theory. First it argues for a metric: maximizing the probability that humans and their technology in space someday reach what Rostow called the “economic takeoff” point where autonomous growth becomes possible, not bound by the rate of growth on earth. Next it discusses three concrete requirements to reach that point: benefits to earth which exceed costs to earth, large and diverse enough “exports” from space to earth, and advancements in technology and infrastructure. Energy from space (ES) is now one of the most promising export possibilities, based on what was learned in the last open US government effort on that topic, “JIETSSP,” led jointly by NSF and NASA. I review several options for ES, and propose a new one which, while slightly riskier, offers real hope of electricity at a price that could compete with coal and fission-plus-enrichment.     

The comovement of US and German bond markets

We use a vector-autoregression, with parameter estimates corrected for small-sample bias, to decompose US and German unexpected bond returns into three ‘news’ components: news about future inflation, news about future real interest rates, and news about future excess bond returns (term premia). We then cross-country correlate these news components to see which component is responsible for the high degree of comovement of US and German bond markets. For the period 1975-2003 we find that inflation news is the main driving force behind this comovement. When news is coming to the US market that future US inflation will increase, there is a tendency that German inflation will also increase. This is regarded bad news for the bond market in both countries whereby bond prices are bid down leading to immediate negative return innovations and changing expectations of future excess bond returns. Thus, comovement in expected future inflation is the main reason for bond market comovement.     

Asymmetric mean-reversion and contrarian profits: ANST-GARCH approach

This paper investigates the time-series evidence of asymmetric reverting patterns in stock returns that is attributable to “contrarian profitability.” Using asymmetric nonlinear smooth-transition (ANST) GARCH(M) models, we find that, for monthly excess returns of US market indexes over the period of 1926:01–1997:12, negative returns on average reverted more quickly, with a greater reverting magnitude, to positive returns than positive returns revert to negative returns. The results are quite consistent when the models are implemented not only for the different sample periods, such as 1926:01–1987:09 and 1947:01–1997:12, but also for portfolios with different characteristics, such as different firm-size portfolios and Fama–French risk-adjusted factor portfolios. We interpret the asymmetrical reversion as evidence of stock market overreaction.     

Institutional theory and accounting rule choice: an analysis of four US state governments' decisions to adopt generally accepted accounting principles

In this study, we use institutional theory to explore how institutional pressures exerted on four state governments (New York, Michigan, Ohio, Delaware) influenced the decision of these governments to adopt or resist the use of generally accepted accounting principles (GAAP) for external financial reporting. We identify resource dependence as a potent form of coercive institutional pressure that was associated with early GAAP adoption. We identify three factors that may lead to initial resistance to institutional pressures for change. First, if accounting bureaucrats are not active in professional associations that promote GAAP adoption, they may miss the educational process that we believe is important to early adoption of GAAP. Second, organizational printing may impede GAAP adoption. Third, powerful interests may impede GAAP if the proposed GAAP legislation is expected to alter the existing power relationships. We found that key accounting bureaucrats in New York and Michigan used “compromise” as an initial strategic response to institutional pressures to adopt GAAP, Ohio's key accounting bureaucrat adopted a “defy” strategy, although the political leadership endorsed an “acquiesce” strategy. While Delaware initially employed a “manipulate”strategy with some success. Delaware did not adopt GAAP for external reporting until a political entrepreneur for GAAP emerged in the early 1990s. Our study suggests that all strategic responses to resist institutional pressures for GAAP adoption will ultimately fail because of the potency of the institutional pressures that result from the well organized professional accounting and governmental institutional fields.
