COVID-19: guaranteed Loans and Zombie Firms

1ZHAW School of Management and Law, Theaterstrasse 17, 8400 Winterthur, Switzerland.
Summary
Swiss firms reacted passively to the COVID-19 crisis, reducing business activities due to falling foreign demand. Government loans present a trade-off between unemployment and future public spending on "zombie firms".
Area of Science:
- Business and Economics
- Crisis Management
- Public Policy
Background:
- COVID-19 crisis significantly impacted Swiss firms' business activities.
- Firms exhibited limited proactive responses, primarily decreasing operations.
- Declining foreign demand was identified as the primary driver of the economic downturn.
Purpose of the Study:
- To evaluate Swiss firms' reactions to the COVID-19 crisis.
- To analyze the impact of the Swiss federal loan program (Bundeshilfe) on business activities.
- To model the trade-offs faced by policymakers regarding financial aid.
Main Methods:
- Survey data collected from Swiss firms between April 7-13, 2020.
- Development of a theoretical model for financially constrained heterogeneous firms.
- Analysis of the economic effects of the federal loan program.
Main Results:
- Firms with pre-crisis difficulties were more severely affected.
- Low loan levels combined with demand shocks can increase unemployment.
- Excessive loan provision risks creating future 'zombie firms' and increasing public spending.
Conclusions:
- Policymakers must balance immediate employment concerns with long-term fiscal sustainability.
- The design of financial aid programs is critical to mitigate negative economic consequences.
- Understanding firm heterogeneity is key to effective crisis intervention.

Factors Affecting Creep
246
In normal-weight aggregate concrete, the hardened cement paste is the primary contributor to creep, whereas the aggregates, being stiffer than the cement paste, are more resilient to stress-induced deformation. The stiffness of the aggregates is defined by their modulus of elasticity, and the more voluminous they are in the concrete, the less it will creep.
Further, the water/cement ratio is critical, as a lower ratio increases concrete strength, thus reducing creep. The strength of the...

Effects of Creep
261
Creep in concrete, the gradual deformation under prolonged stress, significantly impacts the integrity of structures. For reinforced concrete beams, it can be a vital design consideration, as it increases deflection, sometimes necessitating additional design measures. In columns, especially slender ones under eccentric loads, creep can cause buckling, compromising their stability. However, creep can be beneficial in indeterminate structures by mitigating stresses that arise from shrinkage,...

Hazard Rate
236
The hazard rate, also known as the hazard function or failure rate, is a statistical measure used to describe the instantaneous rate at which an event occurs, given that the event has not yet happened. From a probabilistic perspective, it represents the likelihood that a subject will experience the event in a very small time interval, conditional on surviving up to the beginning of that interval. In terms of frequency, the hazard rate can be viewed as the ratio of the number of events to the...

Pozzolans
263
Pozzolans are siliceous or aluminous materials blended with Portland cement. They interact with the calcium hydroxide produced during the hydration of Portland cement and contribute to improved strength and durability of concrete. The pozzolanic activity, a measure of a pozzolan's effectiveness, is typically assessed using the strength activity index, as defined in ASTM C 618-93, which calculates the ratio of the compressive strength of cement mixtures with and without pozzolan.

Fungal Group Zygomycota
449
Zygomycota, previously classified as a distinct fungal group, are primarily terrestrial, saprophytic molds that play a crucial role as decomposers. Recent phylogenetic studies have revealed that these fungi are now divided into two major clades — Mucoromycota, which includes many symbiotic species, and Zoopagomycota, which primarily consists of parasitic and pathogenic fungi. These groups exhibit distinct ecological roles and reproductive strategies while sharing key structural and...
