Forecasting the daily federal funds rate

This paper compares two alternative one-day-ahead forecasts of tomorrow's federal funds rate. The first forecast is a simple random walk forecast in which the forecast of tomorrow's federal funds rate is taken to be today's federal funds rate. The second forecast is an ARIMA model forecast that was allowed to vary with changes in the Federal Reserve System's operating procedures. These two forecasts are compared in terms of their general forecast accuracy and the decision support they provide to a financial institution hypothesized to be borrowing $7 million a week in the federal funds market. Even in cases felt to be most favorable to the ARIMA forecasts, the degree of forecast accuracy and decision support superiority of the ARIMA forecasts is found to be quite small.     

A nonparametric approach to market timing: evidence from Spanish mutual funds

The measuring of market timing abilities in investment portfolios is a relevant and widely analyzed question. Since the traditional parametric methodology can lead to biased results, we apply the nonparametric approach trying to overcome these biases and compare the results obtained by both methods. This comparison can help the readers to understand the role played by the assumptions behind each approach. We confirm the finding previously found in the literature about negative market timing abilities of Spanish equity fund managers. This finding suggests that neither the documented specification problems of the traditional models (heteroskedasticity, outliers and non-normality in financial data) nor the aggressiveness of some misinformed managers explain the poor timing abilities of managers.     

A reexamination of the market efficiency hypothesis: Evidence from an electronic intra-day,inter-dealer FX market

Researchers acknowledge that the evidence of autocorrelation (price dependency) in daily/weekly asset returns provides no conclusive evidence against the market efficiency hypothesis since the holding period of actual speculative positions may be less than a day. Using a high frequency (up to one hundredth of a second), transaction-based, electronic foreign exchange (FX) brokerage data set, we show that dealers in this market tend to close their speculative positions in less than a minute. We provide evidence that there is a significant negative autocorrelation in the rate of return on DM/USD exchange rate. However, when we sample data at frequencies shorter than a minute, profits are infeasible for two reasons: (1) the structure of the autocorrelation pattern is not consistent enough; (2) the largest potential speculative profit derived from the autocorrelation pattern is smaller than the regulated tick size. Our results support the market efficiency hypothesis as dealers have evidently engaged potentially profitable speculation based on price dependency.     

Marshallian labour market pooling: Evidence from Italy

This paper employs a unique Italian data source to take a comprehensive approach to labour market pooling. It jointly considers many different aspects of the agglomeration — labour market relationship, including turnover, learning, matching, and hold up. It also considers labour market pooling from the perspective of both workers and firms and across a range of industries. Overall, the paper finds some support for theories of labour market pooling, but the support is weak. Specifically, there is a general positive relationship of turnover to local population density, which is consistent with theories of agglomeration and uncertainty. There is also evidence of on-the-job learning that is consistent with theories of labour pooling, labour poaching, and hold up. In addition, the paper provides evidence consistent with agglomeration improving job matches. However, the labour market pooling gains that we measure are small in magnitude and seem unlikely to account for a substantial share of the agglomeration benefits accruing to Italian workers and firms.     

The housing market effects of discrete land use regulations: Evidence from the California coastal boundary zone

The California coast line borders some of the most beautiful and expensive land in the entire world. The California Coastal Commission was created in 1976 to protect the coast line and to regulate land use within the coastal boundary zone. This well defined regulatory boundary offers a unique opportunity to study the consequences of land use regulation on nearby housing located in the same political jurisdiction. Using two different geocoded data sets, we document gentrification within the boundary and discuss possible explanations for these patterns.     

Economic fluctuations,market power,and returns to scale: Evidence from firm-level data

Recent research on aggregate fluctuations, coupled with ongoing work in industrial organization, has renewed interest in the existence, magnitude, and cyclical pattern of market power and the extent of increasing returns to scale. By exploiting restrictions from dynamic theory and information from financial markets, we present a framework for generating quantitative evidence on market power and returns to scale. Tailoring the econometric model to firm-level panel data, we calculate the percentage differential between price and marginal cost (the Lerner index) in terms of the parameters from the econometric system. Results for firms in eleven industries indicate that there is a great deal of heterogeneity in the extent of market power. Industries with significantly positive Lerner indices tend to have substantial increasing returns in the production technology. We find that there is only a modest relation between our estimated Lerner indices and traditional measures of market power and that, when market power varies temporally, it is usually procyclical. Thus, variations in the markup of price over marginal cost may help dampen aggregate economic fluctuations.     

Transaction costs and market efficiency: Evidence from commission deregulation

This study analyzes the impacts of explicit transaction costs on weak-form market efficiency within the context of the brokerage commission deregulation in Japan in October 1999, which led to lower commission rates across the market. Applying two alternative statistical tests to both daily and weekly data, we find that return randomness (unpredictability) increases significantly for stocks listed in Japan, but not for the Japanese stocks dually listed in the United States, which are immune to the deregulation. These results suggest an inefficiency loss or an efficiency gain in the Japanese equity market following the deregulation, insofar as randomness proxies for efficiency.     

Labor market rigidities and economic efficiency: Evidence from Spain

In the 1990s, Spain approved two labor reforms aimed at reducing the unemployment level and its volatility. Overall, these reforms involved two measures designed to induce firms to meet their labor needs via adjustment of permanent positions: restricting the use of temporary workers and reducing the amount of severance payments. This paper empirically assesses the impact of these reforms on the allocative efficiency of the labor input employing Petrin and Sivadasan's (2011) value of the marginal product-marginal cost gap methodology. We find a statistically significant increase in within-firm permanent labor gaps following the reforms. These results suggest that restrictions on the use of temporary workers (increasing the probability of hiring fragile workers for permanent positions), when coupled with uncertainty about enforcement of reduced severance payments, could more than offset the reduction in severance payments; hence, the net effect of the reforms could be to increase adjustment costs for permanent positions.     

Default rates in the loan market for SMEs: Evidence from Slovakia

Financial markets in emerging economies are often perceived as more risky than those in developed countries. We investigate whether this is true for loans to SMEs using a unique unbalanced panel of nearly 700 loans made to SMEs in Slovakia between 2000 and 2005. Several probit and panel probit models show that liquidity and profitability factors are important determinants of SME defaults. Moreover, we find that indebtedness significantly increases the probability of default. Liability as proxied by the legal form of SMEs has important incentive effects. Finally, there exist significant differences between sectors. We show that default rates and factors converged to values found in developed financial markets.     

Stock returns and volatility: Evidence from the Athens Stock market index

This paper investigates the volatility of the Athens Stock excess stock returns over the period 1990–1999 through the comparison of various conditional hetero-skedasticity models. The empirical results indicate that there is significant evidence for asymmetry in stock returns, which is captured by a quadratic GARCH specification model, while there is strong persistence of shocks into volatility.     

A new marked point process model for the federal funds rate target: Methodology and forecast evaluation

Forecasts of key interest rates set by central banks are of paramount concern for investors and policy makers. Recently it has been shown that forecasts of the federal funds rate target, the most anticipated indicator of the Federal Reserve Bank's monetary policy stance, can be improved considerably when its evolution is modeled as a marked point process (MPP). This is due to the fact that target changes occur in discrete time with discrete increments, have an autoregressive nature and are usually in the same direction. We propose a model which is able to account for these dynamic features of the data. In particular, we combine Hamilton and Jordà's [2002. A model for the federal funds rate target. Journal of Political Economy 110(5), 1135–1167] autoregressive conditional hazard (ACH) and Russell and Engle's [2005. A discrete-state continuous-time model of financial transactions prices and times: the autoregressive conditional multinomial-autoregressive conditional duration model. Journal of Business and Economic Statistics 23(2), 166 – 180] autoregressive conditional multinomial (ACM) model. The paper also puts forth a methodology to evaluate probability function forecasts of MPP models. By improving goodness of fit and point forecasts of the target, the ACH–ACM qualifies as a sensible modeling framework. Furthermore, our results show that MPP models deliver useful probability function forecasts at short and medium term horizons.     

Migration and gender differences in the home labour market: Evidence from Albania

This paper examines the role of migration in affecting the labour market opportunities of male and female household members left behind. We address this question by analyzing the impact of international migration flows from Albania, where migration is a massive and male-dominated phenomenon. We find that the labour supply of men and women responds differently to current and past migration. Controlling for the potential endogeneity of migration, estimates show that having a migrant abroad decreases female paid labour supply while increasing unpaid work. On the other hand, women with past family migration experience are significantly more likely to engage in self-employment and less likely to supply unpaid work. The same relationships do not hold for men. These results suggest that while left-behind women in Albania may take on the extra burden associated with the migration of male family members, they gain employment opportunities upon their return.     

The characteristics of technically orientated firms: Evidence from the unlisted securities market

The results of a survey of the research, design and development activity of firms listed on the UK Unlisted Securities Market are reported. The significance of different corporate objectives, types of market structure, forms of rivalry, different groups as project initiators, and techniques of project evaluation, is reported. Technically progressive firms could not be distinguished from less technically progressive firms using univariate tests. Multiple discriminant analyses indicated that technically progressive firms operate in markets where products characteristics and advertising are significant forms of rivalry, the growth rate of profits is more important as a corporate objective and the significance of interdepartmental committees as an initiating group is higher than for less technically progressive firms. The latter firms judged price competition and the objective of achieving a target level of units sold as more significant than the former group.     

Subtle discrimination in the rental housing market: Evidence from e-mail correspondence with landlords

We find that landlords practice subtle discrimination in the rental housing market through the use of language associated with describing and viewing a unit, inviting further correspondence, making a formal greeting, and using polite language when replying to e-mail inquiries from a white name more often than to an African American name, they also send longer e-mails and respond quicker to white names.     

Entry regulations and labour market outcomes: Evidence from the Italian retail trade sector

The paper analyzes the relationship between entry regulations and employment in the Italian retail trade sector. In Italy the opening of large outlets is regulated at the regional level. First, by using differences-in-differences estimators the paper presents evidence that in regions with less stringent entry regulations, retail trade employment does not decrease. Second, the paper focuses on the effects of the rules implemented in Abruzzo and Marche, two otherwise close and similar Italian regions which adopted very different policies: the first set tight restrictions on the opening of large stores; the second did not impose substantial entry regulations. The results show that in Marche after the inception of the flexible regulations the share of total retail trade employment in total population increased by 0.8 percentage points more than in Abruzzo. Fiercer competition also led to a recomposition of employment in small retail shops. These findings are robust to a number of checks.     

Inventory management in the just-in-time age

JIT will change our conventional thinking concerning the management of inventories and streamline our methods for inventory control. Proper selection and implementation of these methods will yield substantial benefits by improving customer service, shortening delivery lead times, and significantly reducing inventory investment. It does not, however, eliminate the need for sound inventory planning.     

Inventory management within the supply chain

How can a company reduce its inventory costs as much as 35 to 50% of its current assets? The key to reducing inventory is to evaluate the entire supply chain, including an assessment of procurement, production, and distribution.     

Political and economic influences on the bureaucratic allocation of federal funds: The case of Urban Development Action Grants

The distributive theory of politics predicts that federal budget allocations will be responsive to the committee position of congressmen and their majority/minority party status. But such political allocations are less likely where bureaucrats rather than legislators make the allocative decisions. In such cases we must take into account bureaucratic motivations as well. Niskanen's bureaucratic budget maximization theory emphasizes such bureaucratic maximands and the efficient production of output or activity by the budget constrained bureau. In this paper the two theories are tested using data from the Urban Development Action Grant program, a capital subsidy program operated by the Department of Housing and Urban Development. A set of political and bureaucratic decision criteria is employed as independent variables in a series of logit and Tobit models in order to predict the likelihood of projects being funded and the amounts they will receive. The political criteria are not significant in any specifications, but the bureaucratic criteria suggest an investment-maximizing, risk-avoidance strategy on the part of HUD bureaucrats. Thus the results support the Niskanen theory, but do not support the distributive theory.     

Equity market contagion during the global financial crisis: Evidence from the world's eight largest economies

The global financial crisis (2007–2009) saw sharp declines in stock markets around the world, affecting both advanced and emerging markets. In this paper we test for the existence of equity market contagion originating from the US to advanced and emerging markets during the crisis period. Using a latent factor model, we provide strong evidence of contagion effects in both advanced and emerging equity markets. In the aggregate equity market indices, contagion from the US explains a large portion of the variance in stock returns in both advanced and emerging markets. However, in the financial sector indices we find less evidence of contagion than in the aggregate indices, and this is particularly the case for the advanced markets. The results suggest that contagion effects are not strongly related to high levels of global integration.
