Abstract

The Covid-19 pandemic has had a significant impact on the economy. As a result, many companies were forced to close, and employees lost their jobs. Several economic variables suspected of mediating the impact of the Covid-19 pandemic on unemployment include investment, economic growth, and inflation. This study aims to determine the impact of the Covid-19 pandemic on unemployment in Indonesia either directly or through the mediation of investment, economic growth, and inflation. This research was conducted using panel data regression in 34 provinces in Indonesia in the 2018Q1 – 2021Q4 period. Through path analysis, the results showed that the Covid-19 pandemic has a direct positive impact on unemployment. The economic growth variable significantly mediates the effect of the Covid-19 pandemic on unemployment. Meanwhile, investment and inflation variables do not have a significant effect. This research is expected to provide an objective picture of the impact of the Covid-19 pandemic on unemployment in Indonesia and become a benchmark for policy formulation in dealing with the impact of this pandemic.

Abstract

During the Covid-19 pandemic it became a challenge for the Public Accounting Firm to carry out audit procedures. During the Covid-19 pandemic, physical meetings or communication between auditors or public accountants and a company's clients were limited, so these meetings, which were generally held face-to-face, became online meetings. The main obstacle for auditors or public accountants during the Covid-19 pandemic is that the audit procedures that must be carried out for the 2020 financial statements will be different from the previous year. In general, audit engagements or communication with clients to obtain audit evidence is carried out face-to-face, but to reduce the spread of the Covid-19 virus, such communication is carried out online. Of course, these communication issues must still be guided by Auditing Standard 260 regarding communication with those charged with governance. This study aims to determine the effect of online audit communication and the use of information systems on audit quality. This research is research with the aim of testing the hypothesis. Studies that engage in hypothesis testing usually explain the nature of a particular relationship or determine the independence of two or more factors in a situation. This study uses an explanatory method where the researcher wants to find the cause of one or more problems.

Abstract

Investment is essentially placing some funds at present with the expectation of future profits. The basic thing that an investor needs to know is that there is a risk that follows the profit/return. In determining the proper allocation of funds, an investor needs to consider the company's assets and liabilities. Company assets can be in the form of shares, property, and others. Meanwhile, the company's liabilities include debts and other obligations. One of the sectors whose company value has stagnated or increased during the Covid-19 Pandemic is the financial sector. Securities companies are a sub-sector of the financial sector which has a fairly strong position during the Pandemic. This research aims to determine the weight of fund allocation in each company forming the optimum portfolio and to see the effect of the company's assets and liabilities on the formation of the optimum portfolio. One of the methods used is the Lagrange Multiplier method for model formulation. The results of this study show that the optimal portfolio weight of PANS companies is 16.31% with an allocation of funds amounting to Rp163.612.976,00, the optimum portfolio weight of RELI companies is 83.003% with an allocation of funds of Rp830.029.681,00, and the optimum portfolio weight of TRIM companies is 0.636% with the allocation of funds amounting to Rp6.358.243,00. In this study, it was also found that the greater the percentage difference between the company's assets and liabilities, the greater the company's optimum portfolio weight.
