Branch banking and regional financial markets: evidence from prewar Japan Open
In Japan in the 1920s, several financial crises and government policy led to bank mergers and the consolidation and expansion of branch networks. Using unique historical bank branch-level lending and deposit data, we show that branch banki…

Enhanced CO <sub>2</sub> Emissions Driven by Flooding in a Simulation of Palsa Degradation Open
Climate change is predicted to put most of the permafrost habitats in the discontinuous zone, at risk of disappearing within the next few decades. On a decadal scale, abrupt permafrost thaw may result in larger C losses than gradual permaf…

How scale affects N2O emissions in heterogeneous fields of a diversified agricultural landscape Open
Nitrous oxide (N 2 O) emissions from agricultural soils vary due to factors such as soil organic matter, soil moisture, and crop type, leading to short-term variations and concentrated zones of high emissions, known as “hot moments” and “h…

A Cost-Effective Automatic Chamber for Permanent CH4 and N2O Assessments inWetland Environments Open
Wetland ecosystems exhibit large spatial and temporal variability in terms of greenhouse gas (GHG) fluxes, necessitating new technologies to ensure that they are well-monitored. Both manual and automated chamber-based approaches are curren…

Enhanced CO2 Emissions Driven by Flooding in a simulation of Palsa Degradation Open
With climate change, discontinuous permafrost is thawing rapidly and part of Permafrost-affected peatlands are at risk of disappearing within decades. Thawing in permafrost-affected peatlands can occur gradually (decades to centuries) or a…
