Abstract
Large real shocks can propagate through financial systems, yet the mechanisms through which they do so remain poorly understood. We study whether banks absorb such shocks or instead amplify them through contractions in credit supply. Using the 2010 Haiti earthquake as a natural experiment, we combine newly assembled bank-level, branch-level, and household-level data and exploit spatial variation in earthquake intensity in a difference-in-differences framework. We find that more exposed banks experience persistent deterioration in financial performance: non-performing loans increase by 10–15 percentage points and loan-to-deposit ratios decline by 25–38 percentage points. Linking household and bank data, we identify a borrower-balance-sheet channel through which real shocks propagate into financial fragility. Households in more affected areas experience large and persistent losses in wealth and productive assets, weakening repayment capacity and collateral values and inducing banks to contract lending. Our findings suggest that in low-insurance environments, financial systems amplify rather than absorb large shocks, with important implications for recovery and financial stability.

Abstract
This paper examines how trade credit structures—customer payment delays and supplier payment terms—shape firms’ dynamic transitions into and out of investment financing constraints. Using firm-level panel data and an endogenous switching framework, we show that inter-firm payment structures significantly influence financing regimes, revealing trade credit as a key but under-explored channel of corporate financial flexibility.

Abstract
This paper studies exporting and innovative firms investment sensitivity to days of sales outstanding, suppliers payment terms, and cash flow which are found to be financial factors determining financing constraints. We also advance and test the idea that export intensity and innovation intensity are driving channels of exporting and innovative firms investment potential sensitivity or non-sensitivity to financing constraints. Using Provence-Alpes Côte d'Azur firms level panel data collected between 2005-2014, we find that exporting firms investment is significantly and positivitly sensitive to cash flow and days of sales outstanding, while that of innovative firms is only significantly sensitive to cash flow. Although jointly export and innovation performances vanish firms investment sensitivity to financing constraints. Moreover, exporting firms export intensity is significantly and positively sensitive to days of sales outstanding while innovative firms innovation intensity is not significantly sensitive to financing constraints. Then, export intensity appears to be a driving channel for exporting firms investment sensitivity to days of sales outstanding while innovation intensity is not a driving channel for innovative firms investment sensitivity to cash flow.

Abstract
This paper investigates and contrasts the determinants of four different groups of projects -social, environmental, economic, and cultural- crowdfunding success. Our results demonstrate that while social and cultural projects probability of crowdfunding success is significantly and negatively sensitive to the requested amount of funds, economic projects probability of crowdfunding success is significantly and positively sensitive to the requested amount of funds. Although, environmental projects probability of crowdfunding success does not display a significant sensitivity to the requested amount of funds. Overall, our findings highlight that projects probability of crowdfunding success is an increasing function of financial benefits. Although financial benefits influence is limited to a narrow success. Financial benefits do not influence projects probability of crowdfunding over success.
