The main source of financing is bank loans for Portuguese small and medium-sized entities (SMEs), which implies several constraints to obtaining additional funds. Relying on the argument of Positive Accounting Theory (PAT) that accounting choices are not neutral and on Agency Theory that information asymmetry prevails between insiders and outsiders, we analyzed the impacts of debt on earnings quality, focusing on its level, its increases, and its term of payment. We estimated econometric regressions using panel data with fixed effects over 2013–2019, using discretionary accruals as an inverse proxy of earnings quality. We found empirical evidence that the relationship between debt and earnings quality tends to vary in sign, as the quality of financial information deteriorates with debt, but as debt becomes high, firms tend to increase the quality of earnings. Furthermore, we found that short-term debt tends to decrease earnings quality more than long-term debt. This article aimed to contribute to the prior literature by collecting evidence that debt levels tend to be an incentive to increase earnings management and fill the gap by analyzing the influence of different debt features. This evidence is useful because earnings management may compromise both stakeholders’ confidence and the efficient allocation of capital.

The main objective of this study is to empirically test capital structure decisions in Portuguese family-owned businesses under trade-off theory (TOT) and pecking order theory (POT) and attend to the relationships between family/business interaction and agency conflicts. Family-owned businesses are essential for the development of economies, but the financing logic they adopt is not yet adequately clarified by scientific research, especially as they are more exposed to the constraints of markets imperfections. The specific pattern of business ownership may affect the financing decision and the ability to obtain funds externally. This issue is more relevant in economies where family business initiatives and less sophisticated management strategies are expressive. The greater convergence of interests in family businesses and the consequent decrease in agency costs may lead to higher levels of recognized reputation and thus easier access to indebtedness. The empirical study uses static models and dynamic panel models in order to analyze data from 4,952 Portuguese family-owned firms over the period from 2009 to 2016: the TOT following the partial debt adjustment model, and the POT following the model of the impact of the deficit of funds on debt and the model of the relationship between debt and the determinants of financing. The results of the individual tests suggest that Portuguese family-owned businesses adjust debt at the target ratio, albeit influenced by adjustment costs that keep them distant from the optimal, as well as use sources other than debt when a financial deficit occurs. Although the impact of the financial deficit is greater in total debt ratio, the velocity of adjustment to the optimal level is higher in short-term debt. Evidence from a joint test confirms that both theories explain part of the capital structure of Portuguese family-owned businesses.

We investigate whether accounting information system quality has an impact on the level and efficiency of firms’ investments. While firms’ growth depends on investment and financing decisions, accounting information is fundamental for the decision-making of several stakeholders. We assess the accounting information system quality by discretionary accruals, whereas the investment inefficiency is estimated by the residuals of an investment regression for a sample of 3073 Portuguese SMEs from 27 industries, over the period from 2016 to 2021 using a panel regression analysis. The empirical evidence suggests that firms exhibiting higher accounting information system quality tend to invest more. In addition, firms with a lower accounting information system quality have more inefficient investments, as they tend to engage in more overinvestment, although this is not significant for underinvestment. Therefore, this study provides new evidence regarding the impact of accounting information systems on investment that may be useful for several stakeholders, such as managers, creditors, regulators, and academics, by providing evidence for SMEs, where empirical studies are scarce.

While financial statements are the primary source of information about a firm, they tend to be under earnings management practices, namely to avoid paying tax. Therefore, we aim to examine whether taxes still affect earning persistence in an era of prevalent digital information. For that purpose, we use book–tax differences considering the deductible temporary differences and the taxable temporary differences. In addition, we analyze which of the two earnings components are more affected by taxes, specifically cash flow or accruals. We estimate econometric regressions using panel data to test our hypotheses. Through a sample of 421 small- and medium-sized (SME) Portuguese firms, between 2016 and 2020, we found empirical evidence that earning persistence tends to be lower when deductible temporary differences increase, while taxable temporary differences produce no statically significant effect. Furthermore, our results suggest that cash flow component increases more earning persistence than accruals. Therefore, deductible temporary difference may be an indicator of earnings management activities in these firms. These results are relevant, given the potential negative consequences of earnings management for the efficient decision making of stakeholders and even more because SMEs represent a substantial number of firms in European countries, particularly in Portugal.

The magnitude of the subprime crisis effects caused recessions in several economies, giving rise to the global financial crisis. The scale of this major shock and the different recovery profiles of European economies motivated this paper. The main objective is to look for evidence of contagion between the North American financial market (S&P500) and the financial markets of Portugal (PSI20), Spain (IBEX35), Greece (ATHEX) and Italy (FTSEMIB), in the South of Europe, and the financial markets of Sweden (OMXS30), Denmark (OMX2C0), Finland (OMXH25) and Norway (OsloOBX), in the North of Europe. Considering the period from January 1, 2003 to December 31, 2013, the ARMA-GARCH models were estimated to remove the autoregressive and conditional heteroscedastic effects from the time series of the daily returns. Then, the copula models were used to estimate the dependence relationships between the European stock indexes and the North American stock index, from the pre-crisis subperiod to the crisis subperiod. The results indicate financial contagion of the subprime crisis for all analyzed European countries. The North European markets intensified the relations of financial integration (both in negative and positive shocks) with the North American market, apart from the Danish against the Portuguese. In addition to the contribution made by the joint application of the ARMA-GARCH models, the findings are useful to identify channels of financial contagion between markets and to warn about the effects of possible new crisis, which will require different levels of adaptation by the companies’ financial managers and intervention by the authorities.
