A Consistent Econometric Test for Bid Interdependence in Repeated Second-Price Auctions with Posted Prices

In repeated second-price experimental auctions, the winning bid is normally posted after each round. The posting of these winning prices after each round can result in bids submitted in later rounds to be interdependent with posted prices from earlier rounds. Several approaches in the past have tried to scrutinize their experimental data for value interdependence by regressing bids on lagged market prices or lagged bids and ignoring the inherent endogeneity problem. This paper introduces a formal test for bid interdependence in repeated second-price auctions with posted prices using a dynamic panel model. We then apply this test to formally check the presence of bid interdependence in three datasets used in previous studies.     

Asset pricing and foreign exchange risk

According to the International Capital Asset Pricing Model (ICAPM), the covariance of assets with foreign exchange currency returns should be a risk factor that must be priced when the purchasing power parity is violated. The goal of this study is to re-examine the relationship between stock returns and foreign exchange risk. The novelties of this work are: (a) a data set that makes use of daily observations for the measurement of the foreign exchange exposure and volatility of the sample firms and (b) data from a Eurozone country.The methodology we make use in reference to the estimation of the sensitivity of each stock to exchange rate movements is that it allows regressing stock returns against factors controlling for market risk, size, value, momentum, foreign exchange exposure and foreign exchange volatility. Stocks are then classified according to their foreign exchange sensitivity portfolios and the return of a hedge (zero-investment) portfolio is calculated. Next, the abnormal returns of the hedge portfolio are regressed against the return of the factors. Finally, we construct a foreign exchange risk factor in such manner as to obtain a monotonic relation between foreign exchange risk and expected returns.The empirical findings show that the foreign exchange risk is priced in the cross section of the German stock returns over the period 2000-2008. Furthermore, they show that the relationship between returns and foreign exchange sensitivity is nonlinear, but it takes an inverse U-shape and that foreign exchange sensitivity is larger for small size firms and value stocks.     

Ownership structure,information asymmetry and growth of the firm: Implications from nonfinancial firms listed in S&P500

This paper investigates the association between growth of the firm and ownership structure under conditions of information asymmetry. The objective is to show the effects of information asymmetry (favorable vs. adverse selection) on the choice of the ownership structure that helps firms grow. Our sample includes nonfinancial firms listed in the S&P500 over the period 2000 to 2016. The dependent variable is growth of the firm measured by growth in sales. The independent variables are proxies for changes in ownership structure, individual investors, investment managers, and brokerage firms. Observations are grouped according to level of information asymmetry (high or low) using three proxies for information asymmetry: beta of return on equity (ROE), probability of default of ROE, and q ratio. The results conclude that (a) changes in ownership structure affect growth of the firm positively and (b) the effect of ownership structure is more significant and consistent at low level of information asymmetry. The contribution of the paper is threefold. First, it extends the arguments of corporate governance by showing the impact of ownership structure on growth of the firm. Second, the paper offers robust evidence that growth of the firm is associated with low level of information asymmetry. Third, the paper shows that fundamental financial information can help lessen the level of information asymmetry and thus help firms grow.     

INSTITUTIONAL FAILURES OF SOCIALISM

An effective economic system enlists the co‐operation of all production factors, increasing welfare and reducing transactions costs. The co‐ordination mechanism is activated through decentralisation that shifts decisions on resource control from a higher to a lower level in the institutional hierarchy. Failure to incorporate successful decentralisation into the structure of socialist economies ultimately leads to collapse. Real socialism collapsed because it did not involve decentralisation. Worker‐managed socialism collapsed because of its own inherent contradictions and the absence of properly functioning decentralised price mechanisms.     

Performance evaluation of retail banking services: Is there a trade-off between production and quality?

We propose a two-stage data envelopment analysis model to give an insight on the internal structure of the banking sector and study the important role of service quality in the production process. The first stage deals with the production performance and is related with the optimal use of resources to produce banking services, whereas the second stage deals with the service quality performance using customer-reported satisfaction and loyalty measures. This paper analyzes the efficiency and productivity of 36 branches of a single bank of Greece over the period 2016–2018. The results indicate the existence of a strong trade-off between production and service quality. Further insights of the study indicate that the branch size significantly affects the service quality and overall efficiency. Moreover, the employee assessments by the performance appraisal system of the bank are mainly associated with the service production and not with service quality. Finally, this study presents a managerial decision-making matrix and makes recommendations to help bank managers to improve the retail network performance.     

Corporate Political Activities and the SEC's Oversight Role in the IPO Process

We study how a regulator (Securities and Exchanges Commission; SEC) responds to IPOs that have a higher political profile. We find that IPOs with issuers (intermediaries) that actively pursue political strategies receive more (less) SEC comment letters than IPOs without such actors. Cross-sectional analysis reveals that the IPO's political environment moderates the relationship between social pressure for more corporate transparency and SEC scrutiny. Additional tests indicate that the political activities of issuers (intermediaries) contribute to a less (more) efficient IPO process. Overall, our findings suggest that politically active intermediaries have stronger incentives to accurately portray the IPO financial reporting environment than politically active issuers because they have greater reputational and political capital at stake; quite simply, the former have more to lose. We draw out the implications for theory, in terms of agency and reputation.     

On the macroeconomic determinants of the housing market in Greece: a VECM approach

This study examines the role of the housing market in the Greek economy. We review the literature and assess the interdependence between the housing price index and its macroeconomic determinants within a VECM framework. An equilibrium relationship exists and in the long run the retail sector and mortgage loans emerge as the most important variables for housing. The dynamic analysis shows that the mortgage loans followed by retail trade are the variables with the most explanatory power for the variation of the houses price index.     

Founders’ human capital and the performance of UK new technology based firms

This paper investigates the role of entrepreneurs?? general and specific human capital on the performance of UK new technology based firms using a resource based approach to the entrepreneurship theory. The effect of entrepreneurial human capital on the performance of NTBFs is investigated using data derived from a survey of 412 firms operating in both high-tech manufacturing and the services sectors. According to the resource based theory it is found that specific human capital is more important for the performance of NTBFs in relation to general. More specifically individual entrepreneurs or entrepreneurial teams with high levels of formal business education, commercial, managerial or same sector experience are found to have created better performing NTBFs. Finally it is found that the performance of a NTBF can improve through the combination of heterogeneous but complementary skills, including, for example, technical education and commercial experience or managerial technical and managerial commercial experience.     

Learning by exporting: Lessons from high-technology SMEs

We investigate the learning by exporting hypothesis by examining the effect of exporting on the subsequent innovation performance of a sample of high-technology SMEs based in the UK. We find evidence of learning by exporting, but the pattern of this effect is complex. Exporting helps high-tech SMEs innovate subsequently, but does not make them more innovation intensive. There is evidence that consistent exposure to export markets helps firms overcome the innovation hurdle, but that there is a positive scale effect of exposure to export markets which allows innovative firms to sell more of their new-to-market products on entering export markets. Service sector firms are able to reap the benefits of exposure to export markets at an earlier (entry) stage of the internationalization process than are manufacturing firms. Innovation-intensive firms exhibit a different pattern of entry to and exit from export markets from low-intensity innovators, and this is reflected in different effects of exporting.     

The effect of board composition on the informativeness and quality of annual earnings: Empirical evidence from Greece

This study examines how the informational quality of annual accounting earnings, varies according to the size and composition of the board of directors of publicly listed firms within the Greek capital market. Data analysis over a period of five years (2000-2004) revealed that the informativeness of annual accounting earnings is positively related to the fraction of outside directors serving on the board, but it is not related to board size. Additionally, firms with a higher proportion of outside board members proved to be more conservative when reporting bad news but on the contrary they do not display greater timeliness on the recognition of good news. Finally, firms with a higher proportion of outside directors report earnings of higher quality compared to firms with a low proportion of outside directors. Our results are robust to several sensitivity tests controlling for endogeneity, firm's fixed effects and alternative models for the estimation of discretionary accruals.
