Summary: This paper provides new evidence on the role of intangible assets in reducing credit frictions for SMEs. The findings suggest that identifiable intangible assets can improve firms' ability to access debt and equity finance, with a stronger effect on debt finance. Furthermore, firm age and size can moderate the association between intangibles and access to external finance.

Summary: This paper empirically explores the impact of Internet finance on financial exclusion, finding that city participation in P2P lending is positively linked to the degree of Internet development and negatively linked to the accessibility of traditional finance, with an obvious asymmetry in investment exclusion and borrowing exclusion levels. The findings suggest that Internet finance can weaken the exclusiveness of traditional finance and reduce the asymmetry in investment and borrowing exclusion levels in traditional financial markets.

Summary: This study examines the time-frequency co-movement and network connectedness between green bonds and other financial assets in China. The empirical results reveal that green bonds positively co-move with conventional bonds, but negatively co-move with stocks and commodities. The network connectedness of green bonds with stocks and commodities strengthens over time, while their connectedness with conventional bonds is significant in the short term. The study also finds that the spillover between green bonds and other assets is greater in the long and medium terms. Overall, the study provides practical implications for investors and policymakers.

Summary: This study introduces a new methodology using the irrational fractional Brownian motion model to forecast the numerical value of the fat tail(s) in asset returns distributions. By fitting parameter values to consecutive daily 2-year period returns of the S&P500 index over [1950-2016], optimal model parameter values are obtained, leading to 33-time series estimations. Through an econometric model and auto-regressive analysis, the kurtosis and returns distributions are modeled and forecasted, providing accurate measurements of return distribution shapes and Value at Risk.

Summary: We propose a model that explains the role of investors in information choices and asset prices. The availability of fundamental information varies over time based on investor demand. The research sector generates more information when investors are willing to pay for research. This feedback mechanism results in two equilibrium regimes, one characterized by high prices and low volatility, and the other by the opposite. The low price, high-volatility regime is associated with greater information asymmetry between informed and uninformed investors. Information dynamics move the market between regimes, causing large price drops even without changes in fundamentals. Calibration of the model suggests the important role of information dynamics in financial crises.

Summary: The study shows that uncertainty spikes can undermine the policy-rate-based transmission mechanisms, and asymmetries exist at the firm level where factors such as investment irreversibility, market power, and cash flows influence firms' responsiveness to monetary policy changes.
The effectiveness of monetary policy depends on authorities' ability to reduce uncertainty and target sectors more likely to be affected by policy shifts.

Summary: This paper adopts a real options approach to investigate the effects of economic policy uncertainty (EPU) and monetary policy on R&D investment. The findings show that higher EPU and contractionary monetary policy have a positive influence on R&D investment, while lower EPU and expansionary monetary policy have a negative influence. These findings shed light on the counter-intuitive behavior of R&D investments and can help policymakers anticipate such effects.

Summary: Electricity production in hydrological-dependent systems is influenced by weather phenomena, impacting spot prices. We propose a stochastic process with mean reversion and switching regime component to represent spot price dynamics. Our study on the Colombian electricity market shows that scarcity seasons increase spot price mean, variance, and risk level. The switching regime model with semi-nonparametric distributions outperforms traditional models, making it a valuable tool for resource planning and risk management in electricity markets with high climatic dependency.

Summary: Financial contagion, known as the simultaneous spread of crisis among stock markets due to their interconnection, has a long-lasting effect and is manifested in herd behavior. This study examines the presence of contagion, its transmission channels, and potential herd behavior using worldwide MSCI indices covering the subprime, European, and COVID-19 crises. Results show evidence of contagion during all three crises, driven mainly by investor expectations and their impact on volatility. In addition, during the COVID-19 crisis, the dissemination of information measured through text-based indices played a significant role in market contagion and led to herd behavior.

Summary: This study investigates the response of green bonds and ESG stock markets to the COVID-19 crisis in the US. Unlike the S&P 500 index, the impact of pandemic progress on green bonds and ESG markets is nonlinear: a low (large) level of confirmed new cases of COVID-19 has a positive (negative) effect. Additionally, the implementation of containment policies, such as stringency measures and vaccination campaigns, is viewed positively, but their simultaneous usage is perceived negatively by investors. Overall, this research raises questions about the resilience of investments in green bonds and ESG markets.

Summary: In this study, we estimate the skewness of energy returns and test its statistical significance. Traditional and robust tests for skewness are compared with tests based on the implied skewness in a TGARCH-GC model. The study also examines the impact of skewness on tail risk through the evaluation of VaR and ES accuracy. The results suggest that crude oil and gasoline returns have negative skewness, indicating higher tail risk compared to other energy returns.
