Financial Ratio Adjustment: Industry-Wide Effects or Strategic Management

This paper proposes an alternative model for analyzing financial ratio behavior. The model postulates that (1) firms' financial ratios reflect unexpected changes in industry conditions; and (2) managers attempt to move their financial ratio toward the long-run desirable target. This model is employed to assess the relative weights of financial ratio movement that are associated with these two forces. The results show that changes in financial ratios can be due to both external shocks and strategic adjustment by management. The amount of financial ratio smoothing due to strategic adjustment appears to be substantial. Furthermore, the speed of convergence toward the optimal targets varies across industries and firms of different size.

Data editing and quality of daily diaries in the Italian Time use survey

In the Italian Time use survey, carried out by Istat (Italian National Statistical Institute) in 2002–2003, the coding process translates the sentences reported by the respondents into codes, but association text-code is not a one to one easy linkage, because the respondents describe the activities performed using the common language. So, a process of data editing is requested in order to improve data quality. The possibility to use sentences (recorded in the data entry) has definitely improved the data editing process. The main questions to analyse concern:

The Inflation Hedging Characteristics of US and UK Investments: A Multi-Factor Error Correction Approach

Historic analysis of the inflation hedging properties of stocks has produced anomalous results, with stocks often appearing to offer a perverse hedge. This has been attributed to the impact of real and monetary shocks to the economy, which influence both inflation and asset returns. It has been argued that real estate should provide a better hedge: however, empirical results have been mixed. This paper explores the relationship between commercial real estate returns and economic, fiscal and monetary factors and inflation for US and UK markets. Comparative analysis of general equity and small capitalization stock returns is carried out with inflation divided into expected and unexpected components. The analyses are undertaken using an error correction approach. In the long run, once real and monetary variables are included, asset returns are positively linked to anticipated inflation but not to inflation shocks. Adjustment processes are, however, gradual and not within period. Real estate returns, particularly private market returns, exhibit characteristics that differ from those of stocks.

Small‐sample testing inference in symmetric and log‐symmetric linear regression models

This paper deals with the issue of testing hypotheses in symmetric and log‐symmetric linear regression models in small and moderate‐sized samples. We focus on four tests, namely, the Wald, likelihood ratio, score, and gradient tests. These tests rely on asymptotic results and are unreliable when the sample size is not large enough to guarantee a good agreement between the exact distribution of the test statistic and the corresponding chi‐squared asymptotic distribution. Bartlett and Bartlett‐type corrections typically attenuate the size distortion of the tests. These corrections are available in the literature for the likelihood ratio and score tests in symmetric linear regression models. Here, we derive a Bartlett‐type correction for the gradient test. We show that the corrections are also valid for the log‐symmetric linear regression models. We numerically compare the various tests and bootstrapped tests, through simulations. Our results suggest that the corrected and bootstrapped tests exhibit type I probability error closer to the chosen nominal level with virtually no power loss. The analytically corrected tests as well as the bootstrapped tests, including the Bartlett‐corrected gradient test derived in this paper, perform with the advantage of not requiring computationally intensive calculations. We present a real data application to illustrate the usefulness of the modified tests.     

The Multi-Sectoral Thirlwall’s Law: evidence from 14 developed European countries using product-level data

The paper reports estimates of import and export functions for five technological sectors in 14 developed European countries. These functions have never before been estimated for developed countries adopting a technological classification of sectors. The paper compares estimates of income elasticities found using vector error-correction models employing aggregate deflators, with estimates found using cross-product panels employing product-specific quality-adjusted price indexes recently calculated by Feenstra and Romalis. The results indicate that the income elasticities of imports and exports are higher for medium- and high-tech manufactures, which suggests the importance of moving from the production of simple goods to the production of goods with high technological content. The estimates also suggest that the Multi-Sectoral Thirlwall’s Law holds for the countries analysed, while comparing the estimates revealed that cross-product panels with quality-adjusted prices generate considerably more robust results. The investigation reveals that using a more recent time period generates estimates of income elasticities of demand for primary products and resource-based manufactures that tend to be higher than the estimates found by studies that have used longer time periods, while the opposite holds for low-, medium-, and high-tech manufactures.     

Inspection,testing errors and trade in tainted products

This paper examines international trade and inspection involving tainted products in a model of quality choice, facing fears that globalization is the cause of numerous food incidents. Particularly, we ask the following questions: (i) What are the conditions under which foreign firms choose to produce tainted goods? (ii) Does globalization via freer trade lower product safety? (iii) Why are goods imported even though they are known to be harmful? We show the existence of a free trade Nash equilibrium characterized by production and trade of high-quality non-tainted products. However, free trade cannot prevent the export of tainted goods, because the foreign firm may deviate under different combinations of parameters. We identify self-correcting mechanisms such as nationalism and a political-economy re-allocation of public resources in favor of customs authorities. Nevertheless, we also uncover activities that exacerbate tainted production like errors of testing and sabotage by rival firms.     

Monetization and growth in colonial New England, 1703–1749

We examine econometrically the real effects of paper money's introduction into colonial New England over the 1703–1749 period. Departing from earlier analyses that focus primarily on the depreciation of paper money in the region, we show that expansion of the money stock promoted growth in modern sector activity and not the other way around. We also find that bills emitted for seigniorage purposes had a positive effect on the modern sector, while bills issued through loan banks did not.     

Inflation Dynamics in a Small Open Economy

We evaluate the empirical performance of forward‐looking models for inflation dynamics in a small open economy. Using likelihood‐based testing procedures, we find that the exact formulation is at odds with Norwegian data. Moreover, some of the parameters in the model are not well identified. We also find that the inexact formulation is not rejected statistically using a test based on a minimum distance method. However, confidence regions also reveal an identification problem with this model. Instead, we find a well‐specified backward‐looking model with imperfect competition underlying the price setting, which is a model that outperforms an alternative forward‐looking model in‐sample. The backward‐looking model also forecasts somewhat better than the alternative forward‐looking model, during and after the recent financial crisis.     

Correcting for survey effects in pre‐election polls

Pre‐election polls can suffer from survey effects, causing biases in forecasted election outcomes. We advocate a simple methodology to estimate the magnitude of survey effects, by collecting data both before and after the election. This method is illustrated by means of a field study with data concerning the 2009 European Parliament elections in the Netherlands. Our study provides empirical evidence of significant positive survey effects with respect to voter participation, especially for individuals with low intention to vote. For our data, the overall survey effect on party shares is small. This effect can be more substantial, for example, if political orientation and voting intention are correlated in the sample.
